I'm wondering where seeing "auras" might play into this. It's real. I don't do it but I have a friend who does and she's always spot on about mood shifts or "ah ha" creative moments. Stuff like that.
wouldnt hurt to see ionizing radiation to aviod it, especially in food or water. IR down to 500 nm would give you movie predator vision, VERY useful. The EM wavelengths might get you blinded in a city. ive thought about what the tall mountian around any city would look like in radio. blinding.
You wouldn't see it as "ribbons" or whatever. It would look like a CRAZY bright light off in the distance, and glares of it off of every RF reflective surface around you. Radio stations broadcast at EIRP of like, 100,000 watts. Imagine 1000x 100-watt lightbulbs at the top of a tower shining all around it. that would be way too bright to look at directly. Now imagine being in a dense city, with dozens of extremely high power radio and TV stations all around you, and multiple cell repeaters in basically every building. There would be so much light coming at you from every direction that you'd likely not be able to function. Oh, and you couldn't close your eyes to get away from it because that light goes right through your eye lids.
@@WarrenGarabrandt yea those radio stations with massive EIRP yet everyone (that doesn't have a lick of physics understanding) complaining about "5G" with typicly under 30db (1W?)
Biggest problem I can think of is literally being blinded by the light :) - If you really could see everything, then your eyes would need a way to equalize the energy of the photons of different wavelengths, else the more energetic photons would simply just be too bright, and less energetic photons too dim...
Am red green colourblind, although I do have to look a little longer on it I can tell because they aren't mixed and are relatively large. Problems arise when I have to differentiate overlapping shades of red and green, they aren't well lit or are just a line
I've always thought the mantis shrimp is driven insane by how pretty the world is in 16x Technicolor and then spends its life punching the shit out of it
@@danielmiller2886- That’s wildly cool. They can see polarized light, and a much broader range of electromagnetic spectrum. Unimaginable colors to us, and pathways of light just chilling in their visual of reality.
My husband is color blind...red/green. I bought him a pair of color blind glasses for Christmas one year and he was astonished at all the color there was! He said it almost looked cartoonist to him. And in a big store all these colors he saw was almost too much. He wears them outside all the time so has gotten used to it but that first initial reaction.....I'll never forget it. It was happy yet sad that for 65 years of his life all he saw was bland color. It was the best present I ever bought him!
I've known since I was a child that I can see near UV (UV A). I describe it as looking like "fuzzy purple". When I'm out and about outdoors, the sky always looks hazy, washed out. If I wear UV blocking sunglasses, everything looks clearer, sharper.
I think I have the opposite thing When I look at my phones faceID sensor in a darker environment I can see red light coming from the infrared dot projector and flood illuminator.
I'm mid 40s and don't wear glasses. I was staring at a flea I had removed from my car today. I stared at one of its legs and could barely make it out. After a few seconds and image of the leg appeared in my mind and it was as if I was looking at it through a magnifying glass. How odd! 🤣🧐
Color synthesis is indeed an intriguing topic! One critical thing about CMYK color synthesis that’s often forgotten, is that the dyes used must be _transparent and non-reflective_ . Here’s what I mean by that: When you’re directly painting with light, on aTV screen, you stimulate our cones directly, by lighting up however much red, green, or blue light you want. When you’re printing on paper though, you start with white, which is bright red + bright green + bright blue. Your task is to remove from the white exactly the right amount of red, green, and blue. If you want to print red, you have to remove all of the green and blue from white of the paper. Yellow dye removes all blue light, but lets all red and green light pass through. Cyan dye removes all red light, but lets all blue and green lights pass through. Magenta dye removes all green light but lets all red and blue lights pass through. To present a red color on white paper, you have to give that spot on the paper: yellow dye to remove all of the blue light, and then put on top of that magenta dye to remove all of the green light. All you have left then is red light! But, the light coming off the page is entirely reflected by the underlying white-paper background. The dyes themselves do not _reflect_ light at all (ideally); they only _remove_ color from the white light reflected from the white paper behind it. But the dyes are not paints. Paints are opaque and themselves reflect light. CMY dyes have to be transparent: If the dyes were opaque and reflected light themselves, then this would not work; you would see only the top color - magenta in the above example. For mixing opaque, reflective paints, that’s where the “primary colors” of red, yellow, and blue come from.
Horses are also dicromats, not being able to see the long, red wavelength. Birds of prey are trichromats, but they can also see infrared which is how they can pick out their prey when they are flying overhead. This whole subject is super fascinating!
Really interesting subject! I discovered that I had excellent night vision when I was an instructor in the army. I was teaching recruits night navigation and I could see everything fine while they complained that they couldn't see anything. The downside for me is that I find bright sunlight quite painful and need to wear sunglasses even on overcast days.
My gf hates that I can see quite well in the dark lol. Downside are the headaches from blue light, so I need to wear glasses even inside. Ever go hiking under just the stars?
My natural ability to see well in the dark certainly came in handy during the 25 years I spent as a theatre technician. That and a good sense of direction and distance from my hearing. “Here’s that black bobby pin you just dropped on the black floor.” Kinda combination. The running joke from me was, “What do you mean you can’t see black on black in the dark? What kind of tech are you?” That day ball, though. Somebody, please lower the intensity on that damn thing. Also, when the lights are off in our bedroom, I can see the light from the TVs screen saver through my eyelids. It’s a “black” screen with little yellow dots moving around. The struggle is real. :D
I’ve got the shitty deal from both sides ;-; I have a pretty extreme sensitivity to light, to the point of getting migraines just looking out a window. I also can’t differentiate things in low lighting due to mild colorblindness, so I’m pretty much blind 70% of the time. I’ve got excellent hearing and smell tho, so I guess it’s not the worst thing
Infrared is not heat. It's a common misconception. It's a byproduct of heat. And can cause heat. All hot objects exhibit blackbody radiation, and if they become sufficiently hot, the emitted photons get more energetic and can glow from red to white to blue and a little bit beyond (see: ultraviolet catastrophe). The thing is that infrared doesn't necessarily have to come from a high temperature source. It can be reflected by a reflective surface, or simply emitted by an LED in a TV remote. Of course, a remote LED does produce a little bit of heat in order to radiate a lot of infrared, but an electric heater produces so much more heat than that, comparatively. That's why the skin acting as an eye analogy is flawed. Some of it also has something to do with persistence of vision. Also, in astronomy the vast majority of observed infrared comes from hot objects, and that's where that parallel comes from.
@@neoqueto I'm going to nitpick the nitpick here. (Yes, I know what blackbody radiation is) We *perceive* infrared radiation as heat. In that regard, our skin works as a bolometer; an instrument that measures infrared radiation by the side effects of heating the sensor. Really strong visible light can feel hot, too. But its blinding brightness will dominate our perception of it.
Yes, I was taught the same as you were, wondered where Joe got his info. In the practical sense, yellow & blue mix to create green; thus the primary colors are blue & yellow (& red). These three primary colors were classified as primary because they cannot be created by mixing other colors. What was confusing for me about what we were taught in public school was that black was classified as the absence of color while white was considered the combination of all colors. This black/white color theory was also taught in books on color for artists. But with paints at least, black can be created by mixing of all colors while white cannot be made by mixing colors & is the absence of color.
Both are correct. I know, I know! It hurts the brain. For painting (art class etc) the primary colors are red blue yellow indeed. Which is why you were taught this at school But for LIGHT, the primary colors are red, green, blue (hence RGB). Which is why you were also correctly taught that black is the ABSENCE of light (not paint) and why white is the combination of all of these. Hope that helps
The CMYK acronym stands for Cyan, Magenta, Yellow, and Key: those are the colours used in the printing process. A printing press uses dots of ink to make up the image from these four colours. 'Key' actually means black(for the record other colours have been use, so K is a catch all placeholder). It's called Key because it's the main colour used to determine the image outcome. Great channel thanks for all your hard work...
The perception of it is still vulnerable to the same pre conceived notions that anyone else has. Not having a full compliment of light queues, and the colors are muted by being on a monitor after being recorded on a tri color camera, and compressed with algorithms that are optimized for tri color images. So it's still up to the personal prior experiences and if they are more used to bright or darker environments.
If tetrachromats really want to see what colors match and what don't, look at it through a computer screen or a phone screen. It will limit it to 3 color and will then make them see it like we all see it..
@@squirlmy just read a little about CMYK printing. They made a plate for every color. When the plates hit the paper, they need to be properly aligned. The black plate is the key they are all aligned to. When you get a Sunday comic and the colors are all askew, it is because those color plates are misaligned. It probably doesn't happen much these days because these are old printing techniques. This Wikipedia article has a great example of it. en.m.wikipedia.org/wiki/Printing_registration
I recently read a short story called Seventh Sight, by Greg Egan. The main character is a teenager with a genetic vision problem. Fortunately he lives in a time where he, like his family members with the same condition, have optical implants that correct it. His synthetic retina is covered with artificial cone cells, but only about a third of them are used, the rest are there for redundancy. But these synthetic cone cells are programmable, and can be configured to pick up different wavelengths. The story is about a small group of kids who become aware of a firmware hack that reprograms the extra cells to pick up wavelengths outside of the visible spectrum.
@@ryantwombly720 And good thing too. UV light can badly damage our vision sensing cells, so filtering that out is important. Seeing it is fine, but if it deteriorates our vision over time, it's probably not worth it.
I have deuteranopia. I never knew why people made fun of my clothes choices until I was diagnosed in my 20s. Odd fact: After I had a stroke at age 45 I saw a painful and disorienting spectrum of colors for a couple of years, then my brain adjusted to our comfortable baseline. .
M. Brysch Maybe the stroke affected the visual side of your brain - which then attempted to remap causing this effect. Which then in turn tried to adapt to your visual memories. Hence your "comfortable baseline" , a result of the two ?? My mum had a stroke 2 years ago. Hope all ok with you.
@@tobiasfellmann7692 , the world gets better when we share. =) I initially lost the use of my left arm. A physical therapist visited me purely out of curiosity (statistically and medically I had very little stroke risk) but he came up with theories and therapies. When I transferred hospitals he talked to one of his peers at my new hospital. In less than two weeks my arm worked well enough to type 55 WPM. Brains are strange and amazing.
Also good to see if your marijuana plants are overheating and that you are venting efficiently... those light do produce a lot of heat, and can burn your crop. J/k, kinda... I bet it could be used peacefully doing this.
I have excellent night vision - I only need a little bit of light to see. Back in college, the photography class had a dark room, and nobody else could see in it. But there was a tiny slit in the tarp covering one of the windows, and that was enough for me to see. The drawback is that the light of day tends to be too bright to me. I like to joke that I'm part-vampire.
yep, its coming, and not just IR. I never understood why humans didn't evolve to see IR since it would have been very useful to our old survival skills. (although IR and other wavelengths can be seen if bright enough via harmonics)
But neural link interfaces with the motor context. You would feel infrared. But we already have low resolution, capacity to do that because we feel heat.
@@sadface7457 yes but it could also interface with the visual cortex. Musk talks about being able to add other parts of the brain in the distant future
Even without neurolink, it would be easy to use a VR headset with a computer/camera programed to shift lower frequencies up and give you some control so you can adjust it to make sense of what you see. Say compress anything below a certain frequency and shift upwards. Same could be done shifting downwards for the UV end. Neurolink would simplify it in application, but we could have this now, with existing tech.
@Stephen j Well, and then you've got the harsh vocalists of heavy music genres that have learned to safely utilize their false chords and other throat anatomy.
@ Nah your eyes just get dilated on LSD, so colors are more perceptive, bc your eyes are letting in more light. Colors seem more intense and such, but your not seeing a larger part of the spectrum. Just what you normally see intensified.
DMT is extremely colorful but I'm not sure if we can say whether it temporarily expands the visible spectrum. Would we know? How would we contextualize never before seen colors? I think it is possible but proving it is difficult...
Pretty Normal Media exactly its almost inconceivable it will be very difficult to even put it into words or even pictures, for now it can only be achieved through tripping your self.
I have tetrachromacy, but I also inherited something from my paternal grandfather that allows me to see into the UV spectrum. He was also red/green colorblind, so I find it interesting that we both had this extra color of the rainbow while i was seeing more colors than "normal" and he was seeing fewer. I discovered this UV ability when I was in physics in university and we were measuring light wavelengths and I kept getting purple "wrong". The instructor took some extra time with me to test it and said I was seeing UV - if looking at a rainbow spectrum, it just looks like the purple gets really intense and extended. Rainbows are always a little lopsided to the blue/purple side. And being in a dark room with a black light is not as fun as it is for others.
@@aldionsylkaj9654 yeah looking directly at it, most people do see the fuzzy purple. But for me it's fuzzy purple everywhere in the room. Like a purple-colored lightbulb would be to others.
It's just genetics. I'm a guy and my sight ability is nothing to scoff at. I see things everyone misses. But at the same time I was born with gynecomastia. So we all have our positives and negatives.
Yes, I can see through my eyelids. It's hard because even when my wife is using her phone in a dark room and faced away from me and my eyes are closed, I can perceive the light from her phone screen. Don't know if I have extra thin eyelids or extra sensitive light sensitivity. But I sleep best in a pitch black room.
If you can shine light through your fingers, surely light passes through your eyelids. Flesh is mostly water. No, you can't read words through them, but of course you can tell if you're in a bright environment with your eyes closed. It it were overwise, our eyelids would be meaty slabs.
Many years ago I discovered that if I shined the television remote control into my eye that it caused a painful sensation as if I had shined a bright light into my eye. Although I couldn't see the infrared light being limited by the remote, I could feel it in my eye. I asked my brothers to look into it, but they had no sensation whatsoever. Years later I asked an optometrist about this and she told me that some people can see a little into the infrared spectrum.
Roy Lavecchia Yea it’s crazy that we haven’t tried to map individual rod variations between people to figure out what everyone sees. We can have everyone give a universal name to associate with the color they see, but it’s not the same... Maybe there’s no difference, but judging by how colorblindness can exist, it seems unlikely
1) During a flight physical, the flight surgeon (doctor) located my "blind spot" - the spot on the retina where the optic nerve attaches (no rods or cones). I was surprised when his black pointer in front of a white background disappeared. 2) There are more cones in the central part of the retina than in the peripheral. Conversely, there are more rods in the peripheral part. Test: when looking (unaided) at a star cluster at night, a human can "see it" more clearly if he/she looks a few degrees off axis - where there is a higher density of rods. Keep 'em coming, Joe.
@donutdoode69 yeah apparently it's some kinda slang we probably don't use in USA. Joints? Doobies? Fat spliffs? Go have a few cones. Is that it; am I right? Now you gotta tell us, M8 !
Thank you for the video, Joe! Two wonders I''ve had for a while--- 1-The overlap between red and yellow (orange) seems stronger than any other secondary-primary overlap. In fact it's the only one so wide and clearly distinguishable as a separate colour when viewing the spectrum. 2-Blue seems to somehow be overlapping with a red we can't see, and instead of magenta we see one closer to blue we call violet. It's as if the overlap between yellow and red was made bigger while part of the overlap between blue and green was removed to make space. Perhaps we used to see magenta in the spectrum but for some reason it became more important to identify differences in orange and we evolved as such. . . But still maintained the ability too perceive magenta.
I learned similar differences occur in our ability to smell. Some friends and I were walking thru the Rhododendron Garden in Portland Oregon, and we found that the same flower might smell good, bad, or not at all to different people. And the floral scents detected were different as well. I don't know if this has been researched from genetic, perceptual, or biophysical perspectives.
It's similar to genetic differences between people causing Cilantro or Brussel Sprouts to taste awful to a portion of the population. My Dad likes Cilantro. To me, it literally smells like a stink bug. We had a couple of summers where the stink bugs were bad, and around that time, I decided to buy fresh Cilantro to try it. I spent a couple of minutes searching through the bag, because I was convinced a stink bug got into the bag. It turned out to be the Cilantro. I understand it tastes good to some, and I believe it, but the smallest amount in my food, causes it to taste absolutely terrible.
Like or dislike for the taste of brussel sprouts has been proven to be a genetic difference. It's not about the sprouts. They are just the indicator. It's about the taste receptor.
@JohnR2319881222 well in printing they don't use RGB because they use varying amounts of actual color cartridges. Those cartridges are cyan, magenta, yellow and key (black). A screen doesn't use physical ink to display colors so they can use RGB system. Basically there is no "blue" in CMYK. Lol.
@@martian17 @wing0zero As light is pure energy, it doesn't have a mass and can therefore not make a sound, as sounds and especially sonic booms are due to the compression of air around an object moving faster than the speed of sound. If energy moves faster than the speed of light, it's purely because it a) Has less mass than pure energy i.e. negative mass (Exotic mass or dark matter have been speculated to have negative mass properties) ... Do I need to go on?
"K" is for "Key", not 黒い. This is because even though the combination of Cyan, Magenta and Yellow should produce black upon combination in reality the pigments produce a muddy greenish mess, so a key-line made out of black ink allows the image to have better contrast.
I assumed they used K for black because B was already used in RGB for blue. If you're familiar with RBG then CMYB might seem like it stands for Cyan, Magenta, Yellow and Blue. So they used K instead. Just my assumption without really thinking much about it or looking it up :)
K is used to eliminate the confusion because B is already used in Blue, so they came up with a unique letter used in the last letter of black instead of the first letter.
I'm sure it was a slip of the tongue, but just in case, ALL singers have two vocal cords (four, if you count the false ones), and so does everyone else.
02:57 Monochromats do have a single cone. This cone helps in sharpening images. Having no cones makes images blurry and daylight is extremely bright. 04:46 Not all tetrachromats are the same. The picture you showed is that of a tetrachromat animal with a UV Cone. Antico's cone is between our Green and Red, hence the scientist that worked with her labeled the Yellow Cone. 05:08 Not all tetrachromatic women are aware of their vision because the "yellow cone" might be too close to either the green/red cones that the visual changes are very slim.
I've heard this red-green-blue thing a few times lately. Is my brain more broken than I thought? I've always been under the impression that the primary colors are red-yellow-blue.
They were in school. Apparently there are others, depending on what you do for a living/as a hobby. Makes me angry at how little we're actually taught in public school. (Not just the primary colors, mind you. For instance, did you know there's a special court for victims of vaccine damage? Where was this Federal Claims Court when we learned all about the 3 branches of government in the US? Were you taught about Public Law 102-14 & all its implications? Strange, since it became law in 1991 under the title, *Education Day,* USA & is signed off on every year by every POTUS. What other laws require such dedication?)
Nope you are right! However there are two systems. RGB refers to light primaries (additive system)... Meaning a colour + colour = a brighter colour (I.e. our eyes, computer screens, etc).. RYB refers to the original primaries or pigment primaries (subtractive system) meaning a colour + a colour = a darker colour (I.e. Paint, etc. )
I attended DOD schools except 7th, 8th, 9th and 12th. Fortunately, I was taught about RYB, RBG and CMY before attending public schools during those years.
I just learned there's no right or wrong between RYB and RGB. Primary colors of painting are red, yellow and blue; primary colors of physics and light are red, green and blue. Whaddayaknow!
Signwriter.. I received an honour in colour, the part of the test I gained the honour was colour matching with my eyes then mixing the same colour not knowing the original mix and I had to account for the drying process which made the colour lighter when it was dry paint as opposed to wet paint (darker) No one at the TAFE had ever received an honour and when they asked me how I did it, I replied "I can see and seperate the colours that make the colour I'm looking at in my head.. I even see colours in my imagination that help me recognise individual musical notes.. Each note has a specific colour so if I'm listening to a new song on the radio at work and want to learn it later at home I can remember the colour sequences which is easier than remembering the sound..
That's called synesthesia, I have it too! It's when stimulation of some senses kind of "bleed" into the other senses. For me, numbers and words have colour and texture. 2 is red and smooth, 3 is green and fuzzy. I don't find it as practically useful as yours sounds, though. Lol
9:46 that would make this an awesome super power. You could be a safety inspector for radioactive sites of all kinds not just power reactors. You could be like a blood hound in war times to detect bombs, timing devices that require radiation for its clock mechanism (which many sophisticated clocks now day do), and you could see bio weapons and stuff. Sure you'd be bombarded with noise from stuff we don't normally worry about, but it would be immensely useful. Seeing radio waves would suuuck though.
I just referenced that to someone else... He was saying that having more spectrum data would screw up your brain because it can't invent new colors... But if I understand the Vsauce vid correctly then color is already a perceptual thing and we just agree on names for shared perception, so I figure if you have the brain more data it'd probably just deal with it and render something, we wouldn't have a word for it necessarily but I don't think that'd matter.
@@MrMissionkid There's interesting studies in the etymology of color names that relate to this. Fun fact, There are colors (orange being one iirc) that just didn't have a name in English & other languages until recently because we couldn't synthesize those colors easily. So orange was just red yellow until people actually experienced it on a more regular basis in man made products.
@@MrMissionkid Your brain would 'create' more colors if you could see them. In reality you can't create a unique color because we are bound by the visible spectrum but it's cool to wonder other light would look
Your comments about microwave radiation and your statement that it would be as bright as daytime during the night time would not be true. In fact, it is called "background radiation" because it comes from everywhere and it is very weak. It requires very sensitive microwave receivers to even detect it. So, the notion that it would be bright is therefore simply not correct. But the rest of your video was very informative and enjoyable to view. Keep up the good work. My background, by the way is a retired broadcast engineer with over 30 years of experience with RF.
"It requires sensitive microwave receivers to even detect it". You by any chance read title of the video? We already have it, and we see it, and its bright because WE CAN DETECT IT AND SEE IT
@@64324037 you can see it as static on an old analog tv tuned to an empty channel but it is a small percentage of the static. Originally bell labs researchers thought they had performance issues with a microwave reciever or bird crap on a horn antenna used to develop satellite communications but figured out the noise was a very uniform cosmic background source. One man's noise is another man's signal and they inadvertently provided corroborating evidence of the big bang theory.
There is a calico cat I've been feeding for months outside of where I work. His name that the employees gave him is Sir Fluffynuts. That's all i will say.
Male calico cat There is one exception: A genetic anomaly called XXY Syndrome, which occurs when the male cat has two X chromosomes and one Y chromosome. This can produce a male calico. About one in every 3,000 calico cats is born a male, and, unfortunately, don't live as long as female calicos due to their genetic abnormalities.
FYI, printers use "K" from the old days when printing machines only printed one colour at a time. If you started printing CM or Y before printing black, you would have trouble fitting the black to the colours as they might have been 'out of register' since those colours usually have to fit to the black but not always to each other. Imagine black keyline text filled with a mixture of colours, the colours would be hard to align to each other with no black outlines to fit to. So they printed the Black first and they called it "Key". Also, they didn't label the separations with B, as that may have been confused with blue or another spot colour. (This began in the days of chromolithography when they may have used several 'spot' colours as well as cmy). Also, the 'Key' was not always black! Sometimes it was a brown or whatever when they weren't printing cmyk jobs. Bottom line is that the principal colour that the others would be fitted to was called "Key" and was always printed first and for the last hundred years or so, almost every printing job has had black as the primary for alignment, so 'K' has stuck!
I learnt about it in a genetics course, which went pretty deep into how and why it happens... I don't remember very much about it any longer, but it was really fascinating stuff!
The occurrence of male calico cats is theoretically impossible but they do happen.. Ordinarily, male cats have XY sex chromosomes, while females have XX. The X chromosomes carry the genes for coat colors. Therefore, female cats inherit their coat color from both their queens (XX) and their toms (XY). Male calicos are rare: Only one out of every 3,000 calico cats is male, according to a study by the College of Veterinary Medicine at the University of Missouri. The gene that governs how the orange color in cats displays is on the X chromosome. Females can be orange tabby, calico or tortoiseshell.
Black is listed in the CMYK scheme as "Key." Hence the K. Why "Key?" Think of it as the "master color" (yes, black, not white, lmao you Nazis) that you'd get by combining the other three colors together. It's the key color.
Great video. I love thinking about these types of subjects. I often think about how cool it would be to have a chair with a headrest that "beams" videos into the center of the visual cortex and bypass the eyes. I wonder how high the "resolution" of the image could get when we don't have to rely on the quality of our eyesight.
Had my lenses removed when I was little because of cataracts. All good now. I see the pale beautiful blue when I take off my glasses but sometimes, it can be too bright. I can also see a very faint deep orange when I look at a tv remote LED in total darkness while pressing a button on the remote of course. I am not sure if what I am seeing is infrared or just orange wavelengths as the LED's by product... Gonna need a spectrometer.
Update I found out that a lot of infrared LEDs used in remotes emit a bit of red frequency peak. So that is what I see. I can see pure infrared only of it is very strong like the ones used in cameras.
If you happen to meet someone with Albinism/Vitiligo, have a look at their skin in daylight. Apaprently it glows a little in the ultraviolet spectrum compared to normal skin.

"It's always interesting when you find out that somebody else can perceive something that you can't." Only if they have a point of reference to relate to your perception. Without a relatable point of reference, descriptions of a new sense have difficulty connecting. I've dealt with that for almost a decade now.
"Let's talk color theory. Actually bare with me. This is cooler than it sounds." These statements drive me crazy. NOT because the person saying them said them, but because there are people out there that need be told. If you come to a science or an information forum, and don't want the science or information, then .. well you're in the wrong place. Lol
If I bare with you we would strip at the same time or perhaps moon each other. But to bear with you would mean we are sharing the load. Strange language we speak.

Late to the party but, I’m a photographer who shoots primarily in IR/UV. I utilize a lot of false color IR which mixes some IR into the visible light spectrum (VLS) and creates red/magenta vegetation. The camera is actually converted to “full spectrum” and when you white balance on something neutral the imagery is washed out with a pink tint. Super interesting.
Yes I do to. The pink hue is because there is an abundance of NIR light hitting the sensor. There is a lot more IR light coming from the sun than visible or UV. Vegetation is super reflective to NIR light (a lot of things are) therefore it appears as monochromatic or the same color. Depends on which filters you use of course.
Colorblind. I have to keep reminding people that the "green" wire looks exactly like the "red" wire to me. Yea, don't ask me if a line is hot unless it has a label on it. ⚡😎⚡
Where are you from? What is the wiring coding over there? In Europe we have, brown for live, black for switched, blue for neutral, yellow/green for earth.
True but some painters still go by that. You also have value i.e. How dark something is, and you really cannot mix a light yellow. Yet red is more saturated, more useful, and blue is darker than the cyans...it would be a greener blue and a purpler red too so its just a renaming sometimes,or bc those pigments are expensive, or translucent. But yes its technically incorrect. Except until you make a paint set. So is the concept of getting all colours from 3 paints because you can find a pigment more saturated, or a different value to the mix of cmyk or rby.
Red, blue , and yellow are correct for mixing pigments. RGB is correct for mixing light. CMYK is correct for printing since the 4 color process doesn't mix the colors. They are individual tiny dots carefully aligned to trick your brain. ( Although, one might argue that the brain isn't really tricked, sInce it is able to put all that information together instantaneously!😂)
Great video as usual.....I had diabetes from 18 yrs old to 40. At 40 I removed one food from my diet and my glucose levels dropped drastically and most of my symptoms went away. Shortly after I needed glasses. Then my glasses wouldn't work anymore so I bought stronger glasses until the 3.5x weren't helping me see. I went for a job interview at Bell and I failed the eye test and he told me that I was color blind. All I could see was different shades of grey and extremely blurry. Years later I checked my glucose levels expecting a 5.6 but I got a reading of 3.2. Didnt know what low blood sugar meant but I did not associate it with my blindness. I then replaced beer with energy drinks ( which I usually never consumed ) and my glucose levels began to move up near the 5.6 again. 6 months later I noticed a slight change in my eyesight. A year later my eyes improved further where I didnt need glasses anymore but they were not perfect because I still had problems with low light conditions. It's now 2 and a half years since I began drinking the energy drinks and my eyes are almost perfect again and I can distinguish color again. I beat diabetes Glycemia and blindness without a pill or medical doctor. After my eyes came back I noticed I was able to perceive invisible things like wind and figured out the inner workings of a savonius verticle axis wind turbine using my perception and was able to get a savonius turbine to spin at 32X the speed of the wind when they usually spin at 1X. Diabetes does NOT effect your eyesight but the opposite of diabetes Glycemia does. Diabetics who loose there eyesight is not due to high glucose levels but over medication of insulin which drops your sugar levels way too low which causes blindness and color blindness. I hope this helped. Joe did I mention great video as usual.
Crazy Contraptions so what’s the secret? What is the one food you replaced that brought glucose down? Why not just say. Or maybe it was beer. I am confused.
Anything that gets you stonned such as beer weed hard drugs sleeping pills pain killers do so by lowering your glucose levels and that's what gives you the buzz. Sugar and carbs increase your glucose levels and are our fuel for our cells. Sodium nitrate does not affect present glucose levels but slowly increases fasting glucose levels and over time the increase in fasting glucose levels adds up and diabetes sets in. By removing this poison out of my food my fasting glucose levels dropped from a 20 to a 3.2 .When I removed the beer glucose levels went up. When I added sugar glucose levels moved up to a 5.6 where it is now. I hope this helped if need anymore info please dont hesitate to ask.
@@frankgiancola7 Sodium Nitrate Vs. Sodium Nitrite. Did you also remove sodium nitrite also ? What about salt ? Plus there are more naturally occurring nitrates in a kale salad than a pound of bacon, how can that be bad? Thanks
@@rainerrain9689 Sodium nitrate and sodium nitrite both raise your sugar levels over time. They are both equally bad for glucose levels. After consuming them my glucose would not change and that's why it was so hard to pick out which food was causing the problem. Over time nitrates increase your fasting glucose levels a tiny bit at a time where it is not noticeable from day to day but over a span of a week or even a month those tiny increases in glucose levels are noticeable and as years go on glucose levels millimeter their way up until symptoms began to appear. At 18 years old I began getting restless and my feet began to get itchy and I began to get edgy. Then my appetite slowly began to increase. As the years went on all the symptoms worsened until I couldn't sleep anymore at all. My appetite was ferocious. I would eat 5 times before lunch time and still be hungry. My mouth was really dry and my mood was worsening. My feet were like ice and really itchy. Some days I would walk with a limp. I was always cold and my hair looked like steel wool. For years I was removing one food at a time over a weeks period and did not notice any changes until I removed the salami sandwiches hot dogs and bacon and this was a few months before I turned 40. I had a welt on my foot for a few months that wouldn't heal and I thought I would loose my right foot. After removing those foods my glucose levels plummeted from the normal 20 reading I was getting. My welt went away and feet came back to life. My mood was really good after that. My ferocious appetite dwindled to an appetite of a bird. A month later I ran for the first time 10 km and still do today without even breaking a sweat and I'm 55 years old. The only symptom that remained was my restlessness and my eyes were still good. A few years later thinking my glucose problems were solved my eyes deteriorated from perfect to blind. I then checked my glucose levels from a freind who had a glucose meter and It red 3.2. Then i increased my sugar levels by consuming energy drinks and i quit drinking because drinking and low blood sugar dont mix as i found out. I would have one beer and i was completely drunk. It's been 2.5 years since i had a drink nor do I crave one. In the last 6 months my last symptom went away and now I am able to sleep again. Sea salt is good for you and table salt has tiny grains of sand in it which scar your arteries as they circulate which create plaque on the artery walls. Most of the veggies I eat are from my garden and I DONT use sodium nitrate as a fertilizer as most farmers do. If farmers dont follow the guidelines put place by the govt. Then they dont receive any funding so that's why almost all our veggies have nitrates in them. I hope this helped if you need any more info dont hesitate to ask because there is so much I learned about my health over the past years which I did not read from anywhere and are from my experiences with diabetes and glycemia. Diabetes does not come from over sugar consumption but from sodium nitrate. Over sugar consumption lowers your fasting glucose levels as your body reacts to the spikes in sugar. Blindness does come from diabetes but it comes from glycemia. I hope this helped.
In the mid-'90s, my profession as a commercial photofinisher, transitioned from analog and optical to digital and optical. Here's how the RGB/CMYK difference was explained to me. (This was mostly to address the printing process - think of a darkroom enlarger used to expose photographic paper vs an ink-filled printer used to transfer an image onto office paper.) RGB is the visible light model. It's how our eyes see colors of light. CMYK is the reflective light model. It's how our eyes see colors of light reflected off of objects. 0% of RG & B in light = black 100% of CM & Y reflecting from paper falls short of black due to ambient light dirtying it up (it's a dark grey). Black ink is added to compensate for this. These are opposite spectrums: Red is opposite Cyan in the spectrum Magenta is opposite Green in the spectrum Yellow is opposite Blue in the spectrum Black is called K to avoid confusion with Blue and the K is referring to the K at the end of the name. (edit - after posting this, I did some internet searching and found that K stands for Key, as in the Key Plate in a 4-color printing process.)
The CMB is very diffuse, like near-absolute zero levels of energy. So I doubt microwaves would light up the night. At least not from that alone. You'd be able to spot some of the brighter neutron stars, and that alone makes it worth it.
It is semi diffuse but it does provide a hiss for radio telescopes attuned to that frequency. In fact the CMB was discovered by a telescope being set up to pick up microwaves and when they started looking at the data there was a hiss or static they couldn't get rid of. So it is significant, but I also do think manmade low frequency radiation would drown pretty much everything else at that frequency range out.
Your comments about seeing ultraviolet caught my attention because I had my lenses replaced several years ago because of cataracts and for about a week after that everything had a pinkish hue to it. Occasionally I still see it if I've been in REALLY bright sunlight for more than a couple minutes then go inside or somewhere not as well lit.
It was for about a minute or two in one episode, until the computer was overwhelmed by the data stream. [EDIT] Sorry, no, there was another episode, where Geordi was 'brainwashed' to be used as an assassin to kill the Klingon Chancellor. (Yes, I am a total Star Trek geek.)
So, I'm stereo blind which means I can't see 3D. 3D movies look pretty flat to me. I have a hard time with depth perception. That might be worth talking about.
@@themikeshow I think if one eye is just slightly off it would create it, so they don't fully line up. I've had that at times, or times where I get hyper 3d....not sure which, it's a bit distracting where like a bush is suddenly very 3d, but never been able to for sure tell, it's more like seeing in perspective. But not 100% sure again :> Just know that 3d movies or view master felt a bit different then what I usally see heh.
How do you cope with stairs? I did an experience experiment in my ASL class for the blind/deaf unit, I had a small hole of sight and my depth perception caused me to have serious issues with going up and down the stairs...
The reason why we see magenta is that our brain adds the two colors, the same with the other combinations. It not that we see in between those colors, it is our brain combines the colors. By the way I am a photographer. Back when I was growing up the three primary colors for pigment were red, yellow, and blue. Printers used those colors to print pictures using those along with black. Color photos in magazine needed the photos to be taken with "transparency" film (like slide film). However that must have changed before the 1990's, because when I shot covers for a magazine called "Media ByPass", they specified negative film. That may or may not been because they may have just sent prints. While printers used R,Y,B, photographers always used CYMK when in the darkroom. Curious.
I've noticed the same thing. Mostly on really bright days though. Red will seem a bit faded for my right eye compared to my left. Most of the time I can't tell any difference though.
Im in my 30s and i just noticed this the other day when i was staring at the asphalt. One eye is "cold" and the other "warm"..its very annoying now that im aware of it lol
When my son was about 3, I noticed he kept shutting one eye and then the other. He explained he could see the colour blue nice and bright in one eye, but not in the other. This was indoors and so nothing to do with looking at the sun or at bright lights bleaching the eye, because he says it's still the same years later. So I'm guessing some people have uneven numbers of cones in the eyes, or even one eye that has a total absence of one or more cone type?
I’ve recently wondered about this. It would be very interesting. I really liked your comment about us already doing this. People don’t think we are evolving but our technological advances are us evolving. Our technology are a huge part of us now so we shouldn’t discount that. Thanks for sharing
My three older brothers and I used to point an old television remote into our eyes as a kids and I definitely used to see a purpley red flash although they did not, however I can confirm that I no longer see this with repeated tests as an adult. Im assuming either the infrared sensitivity is prone to degradation as we age, or I and all of my brothers permanently damaged our eyeballs....😅
Well i have three older brothers who also tried and never saw anything, being the youngest sibling i have always assumed that kids just have better eyesight, if you think about it seeing in infrared as children could have boosted our survival rate quite significantly a couple thousand years ago if we got even the faintest glow of predators before an attack. Not to mention 700nm is red that we can see already, infrared sits literally just after that at 750 nm to 1 mm so its actually pretty likley that we can see atleast some of the spectrum, especially as children before our eyes begin to degrade. Check this out- its always under super specific conditions, dark room, laser in eye ECT www.sci-news.com/biology/science-humans-can-see-infrared-light-02313.html
@@grumpyaustralian6631 you're wishing very hard here. Interesting theory about possible evolutionary advantage, but it's a lot to base on essentially anecdotal evidence.
@@squirlmy you were literally just told in the video above that numerous studies confirm humans can see infrared when shined directly in the eye in a dark space so anecdotal evidence aside, its a fact, we can. Im definitely not suggesting my sample size of one is at all usable evidence of us seeing in IR, just stating personal experience, i am also fully aware correlation does not equate to causation dw.
Whenever I'm stressed out, my peripheral vision flashes everything that's red, it's really trippy. Another interesting thing I noticed is that throughout my life I had several arguments when I see something as greenish blue and people say its blueish green.
Great video. I was hoping you would talk about the biological requirements of being able to see those other wavelengths. Like how we would need to have gigantic eyes in order to be able to see the longer wavelengths of radio waves.
I JUST FOUND OUT IM A TETRACHROMATIC!!!!! THIS EXPLAINS SO MUCH!!!! I was really confused at how ANYONE could see that dress as being gold or w/e instead of blue (optical illusion that because a huge internet thing a few years ago) EDIT: oh nvm, I just found that computer screens can't (apparently) produce the light needed to test it.
On the topic of being able to see infrared. Did you know that if you let your eyes adjust to the dark long enough, then look at the IR LED on the front of your TV remote, you can ever so slightly see a dim brownish-red light flashing. Not sure if everyone can see it but I could, it's just very dim though.
You can also see it through your phone camera. OH! an it can blind you because your iris won't adjust to filter out light intensity that it can't see. So if you stared into an ir spotlight it would be dark and painless but you'd go blind without noticing it.
Interesting. I know most digital cameras can see IR. They have an IR filter, but it's almost never fully effective, and the sensor can pick up near IR... On another note, the human retina can detect UV light, but the lens filters it out. (for good reason, since UV light damages the retina) The things described by people that have had something happen to their lenses is... Interesting. (usually this is caused by cataract surgery)
@@foolapprentice3321 I mean maybe if you stared at it non stop for like 10 mins straight an inch from your eye. But it won't do any lasting harm to hold the button in for a few seconds and look at it. Think about all these "ghost" TV shows and their night vision cameras in tight spaces looking at the hosts reaction, they have a far more powerful IR light shining straight in their dilated iris and they're fine. A TV remote won't do you any harm mate.
Our brain might be overwhelmed by all that new information , we'll probably need a neuralink or something better to add extra layer of processing power to our brain.
Yeah, I don't think our visual cortex is built for that. But... Certainly it might learn to adapt a little. Probably doesn't have the 'processing power' to deal with that much information though.
@@KuraIthys oh I would like to think that if say, we could hijack and through training add some extra functionality to the focusing systems of our eyes we could use that to move through the ranges of spectrum perception available on whatever eye "prosthesis" used.
wolvenar ... or just as was described in a ST:NG episode, Jordi shifts his attention around the spectrum. He only bothers with IR one moment, then UV the next, x-ray the next. Just like we only really concentrate on the centre of our vision and hardly any time on the periphery.
Loved the video! My 'extra' perception is I have excellent hearing and when tested my hearing moved up to 22khz, 10% higher than what humans should hear to. Needless to say, certain sounds to almost feel like they hurt... Peace! ✌️
I do have a few weird things with my senses, such as the fact that even though I have trouble seeing distance, I can see better than most people the differences in color, and I have control over what I see and how, like certain loading circles I can make spin the opposite direction. I also can get true tulle vision, were everything but what I am focused on becomes part of my peripheral vision. I can focus on things in my peripheral vision while still looking strait, like in a mirror I can look in a direction and focus on my eyes still looking in that direction. Other senses are weird as well, with my hearing being shifted slightly to higher wavelengths than normal people, but not hearing all low wavelength sounds. My smell and taste are good enough that I can smell/taste some things once and be able to tell later that a different smell/taste is the same. What I smell I will also taste. I can also taste metals by looking at them sometimes, such as looking at a rusty bumper I will taste iron. I have a pain tolerance that makes me not able to feel most high intensity pain but low intensity, or sharp, quick pains I will feel, like stubbing a toe. This includes exhaustion, were I if pull past the low exhaustion I will not feel tired after. I don't feel hunger at all, and only eat by checking the time. My vestibular sense are not perfect either, were I don't get motion sickness from any movment, not matter for how long or fast I am moving, which is mostly spinning.
A former co-worker was in the army and when it came time to pick out troops in the field who were hidden by camouflage he got 100% because to him the camo stuck out.
"High energy gamma rays wouldn't be to hard to deal with." I've never heard those words put together like that before. It's hard to think of a scenario where I will hear them in that order again.
I’ve started to believe that my grandmother is a tetrachromat. She seems to see dirt where the rest of us see none. Gets annoying because where people would see something as spotless, she considers a “pig sty.” Where as for me, the oldest grandson, all reds look the same to me, and green is one of the dullest colors to me.
Great animations, vision is so cool. Always wanted glasses that could see IR and UV. I do have microscopes and telescopes to see cool stuff too. Or glasses to see even more RED as I'm red green color blind and am curious what normal people are seeing. Never knew that until 7th grade in the library when I looked at an Ishikawa diagram and saw different numbers in the circle of colored dots. My older sister thought I was giving her the wrong color crayons on purpose all these years. I did have a knack for finding tomato hornworms in the garden.And mowing bright orange toys camouflaged in the grass. I can see a green stop light from very far away, but in the daytime some red lights are hardly lit up for me. Hey I did recently join Brilliant maybe old guys can learn new stuff.
K stands for key. Black is not part of the chrominance layers but is rather a luminance layer called key plate in the print industry. You have the same in video signals. The B&W image is the luminance layer. And the chrominance is added on top of it with separate channels for each color or in a single chrominance signal with less resolution (color definition does not need to be very precise). In the eye the rods see the luminance. The cones see the chrominance. There are 3 times more rods that specific cones.
Okay, without first even watching the video, if you could see every wavelength in the spectrum, my guess is that you would become unrecoverably insane in the first 30 minutes.
If we augment only eyes but not the brain's ability to process those signals, yup. Not insane, but we'd just go with eyes closed due to the "noise". Eye is just the collector of information - it is the easiest thing to do in the whole chain. The problem is always the processor part. Think for instance the radio-telescopes. Shitloads of data... that would be useless unless we had clusters of supercomputers working on them. Then it's no problem. Same with this - it all depends on the brain. If it remains the same, sure, crazy it is. Even with visible light currently, too much of different wavelengths at the same time and our head hurts after a while. But any broadening of the humanly visible spectrum will HAVE TO be accompanied with brain augmentation. If anything, brain needs to know what to do with those signals it receives. If you just convert the gathered signals and convert it in current brain capacity, it would not make any sense. It would just see more of the same colors. And that's the thing, you can't think of a color you have not seen. Brain is the key here, not the "eye".
@@Wustenfuchs109 It'd definitely change your perspective, but I'm guessing the brain as is could work it out to a point. Not if you are going full spectrum, but if you boosted the available wavelength data by 20-50% it could probably learn to deal. The colors aren't a big deal imo, the only reason you know to call a red thing red is because we all agreed on the name, see the Vsauce video "is your red the same as my red" or something like that, green and red strawberries on the thumbnail. Anyway, your perception is already weird when you learn about it.. the brain would probably say "that looks different" if the data allowed for it, and then render something. You'd never question it unless you could switch back and forth from having it or not.
It's not strange at all. Each organism evolved in its environment to have the type of senses that gave it the best advantages at reproducing in that environment (and thus passing on the genes that made them successful). Humans that could differentiate colour had a survival advantage, bees that can see certain flower markings enable pollination and also get food (and with the flowers that make themselves the most visibly attract also having a survival advantage, there is co-evolution) and pit-vipers that can track the heat of a warm-blooded mammalian rodent after having injected it with venom, thus taking its time to follow along and find the dying prey, it also had a survival advantage. "Nothing in biology makes sense, except in the light of evolution." - Theodosius Dobzhansky
Bees can actually see visible, UV, AND infrared. They have some of the best eyes in the animal kingdom! Not nearly as impressive as the Mantis Shrimp, but almost certainly the most impressive non-aquatic eyes!
@@ntactime_w3488 I didn't say or intimate it was brand new. I just said it's the reason why Alexander is mistaken to think those different adaptations are strange. Thanks so much for your utterly pointless sarcasm (sarcasm) ;)

One cool side effect to being able to see all wavelengths would be that you could tell where the wifi or cell signals are strong enough.
I'm wondering where seeing "auras" might play into this.
It's real. I don't do it but I have a friend who does and she's always spot on about mood shifts or "ah ha" creative moments. Stuff like that.
wouldnt hurt to see ionizing radiation to aviod it, especially in food or water. IR down to 500 nm would give you movie predator vision, VERY useful.
The EM wavelengths might get you blinded in a city. ive thought about what the tall mountian around any city would look like in radio. blinding.
You wouldn't see it as "ribbons" or whatever. It would look like a CRAZY bright light off in the distance, and glares of it off of every RF reflective surface around you. Radio stations broadcast at EIRP of like, 100,000 watts. Imagine 1000x 100-watt lightbulbs at the top of a tower shining all around it. that would be way too bright to look at directly. Now imagine being in a dense city, with dozens of extremely high power radio and TV stations all around you, and multiple cell repeaters in basically every building. There would be so much light coming at you from every direction that you'd likely not be able to function. Oh, and you couldn't close your eyes to get away from it because that light goes right through your eye lids.
@@WarrenGarabrandt yea those radio stations with massive EIRP yet everyone (that doesn't have a lick of physics understanding) complaining about "5G" with typicly under 30db (1W?)
Biggest problem I can think of is literally being blinded by the light :) - If you really could see everything, then your eyes would need a way to equalize the energy of the photons of different wavelengths, else the more energetic photons would simply just be too bright, and less energetic photons too dim...
The chart at 6:04 displaying the genes of colorblind boys is red and green and cannot be seen by colorblind people. Great
Oops! : )
Am red green colourblind, although I do have to look a little longer on it I can tell because they aren't mixed and are relatively large. Problems arise when I have to differentiate overlapping shades of red and green, they aren't well lit or are just a line
Yep. That was frustrating.
Hahaha xD
Well, they see something, just not what colour seeing folk see.
I've always thought the mantis shrimp is driven insane by how pretty the world is in 16x Technicolor and then spends its life punching the shit out of it

And the weird thing is that they don't appear to utilize those extra colors they can see.
@@danielmiller2886- That’s wildly cool. They can see polarized light, and a much broader range of electromagnetic spectrum. Unimaginable colors to us, and pathways of light just chilling in their visual of reality.
My husband is color blind...red/green. I bought him a pair of color blind glasses for Christmas one year and he was astonished at all the color there was! He said it almost looked cartoonist to him. And in a big store all these colors he saw was almost too much. He wears them outside all the time so has gotten used to it but that first initial reaction.....I'll never forget it. It was happy yet sad that for 65 years of his life all he saw was bland color. It was the best present I ever bought him!
A beautiful story....❤️❤️❤️

I am red green color blind as well, but the only thing the glasses did for me was make yellows and blue stand out more..
@@danielmiller2886 Yeah....I was really nervous that they wouldn't work for him. Because they don't always. But thankfully they did!

Why K in Black:
• B was already used (Blue)
• It stands for Key which is the overall brightness.
• You can also say it is the K in the word blacK.
Yes, K stands for "Key". B isn't used for Blue, that's Cyan, abbreviated C.
FriedrichHerschel B is used for blue in RGB Cyan is for CMYK
Bah, K is for Kewl, because we all now black is Kewl.
There is no "k" in the word *censored by RUclips*
Second what kingpest said. In a print shop all colors are lined up to the black plate or the key plate.
I've known since I was a child that I can see near UV (UV A). I describe it as looking like "fuzzy purple". When I'm out and about outdoors, the sky always looks hazy, washed out. If I wear UV blocking sunglasses, everything looks clearer, sharper.
Same! I always thought I was crazy as a kid only barely able to see clouds on a hot day
"Fuzzy purple" is a great way to describe it.
It's because UV light scatters more and there is less on the surface, everything is hazier.
I think I have the opposite thing
When I look at my phones faceID sensor in a darker environment I can see red light coming from the infrared dot projector and flood illuminator.
I'm mid 40s and don't wear glasses. I was staring at a flea I had removed from my car today. I stared at one of its legs and could barely make it out. After a few seconds and image of the leg appeared in my mind and it was as if I was looking at it through a magnifying glass. How odd! 🤣🧐
Color synthesis is indeed an intriguing topic! One critical thing about CMYK color synthesis that’s often forgotten, is that the dyes used must be _transparent and non-reflective_ . Here’s what I mean by that:
When you’re directly painting with light, on aTV screen, you stimulate our cones directly, by lighting up however much red, green, or blue light you want.
When you’re printing on paper though, you start with white, which is bright red + bright green + bright blue. Your task is to remove from the white exactly the right amount of red, green, and blue.
If you want to print red, you have to remove all of the green and blue from white of the paper.
Yellow dye removes all blue light, but lets all red and green light pass through.
Cyan dye removes all red light, but lets all blue and green lights pass through.
Magenta dye removes all green light but lets all red and blue lights pass through.
To present a red color on white paper, you have to give that spot on the paper: yellow dye to remove all of the blue light, and then put on top of that magenta dye to remove all of the green light. All you have left then is red light!
But, the light coming off the page is entirely reflected by the underlying white-paper background. The dyes themselves do not _reflect_ light at all (ideally); they only _remove_ color from the white light reflected from the white paper behind it.
But the dyes are not paints. Paints are opaque and themselves reflect light. CMY dyes have to be transparent: If the dyes were opaque and reflected light themselves, then this would not work; you would see only the top color - magenta in the above example.
For mixing opaque, reflective paints, that’s where the “primary colors” of red, yellow, and blue come from.
Ok. This comment was the most educational one I read this week. More informative than the video maybe.
Horses are also dicromats, not being able to see the long, red wavelength. Birds of prey are trichromats, but they can also see infrared which is how they can pick out their prey when they are flying overhead. This whole subject is super fascinating!
Really interesting subject! I discovered that I had excellent night vision when I was an instructor in the army. I was teaching recruits night navigation and I could see everything fine while they complained that they couldn't see anything. The downside for me is that I find bright sunlight quite painful and need to wear sunglasses even on overcast days.
Ian Petrie
You & me both!
My gf hates that I can see quite well in the dark lol. Downside are the headaches from blue light, so I need to wear glasses even inside.
Ever go hiking under just the stars?
My natural ability to see well in the dark certainly came in handy during the 25 years I spent as a theatre technician. That and a good sense of direction and distance from my hearing.
“Here’s that black bobby pin you just dropped on the black floor.” Kinda combination.
The running joke from me was, “What do you mean you can’t see black on black in the dark? What kind of tech are you?”
That day ball, though. Somebody, please lower the intensity on that damn thing.
Also, when the lights are off in our bedroom, I can see the light from the TVs screen saver through my eyelids. It’s a “black” screen with little yellow dots moving around. The struggle is real. :D
I’ve got the shitty deal from both sides ;-; I have a pretty extreme sensitivity to light, to the point of getting migraines just looking out a window. I also can’t differentiate things in low lighting due to mild colorblindness, so I’m pretty much blind 70% of the time. I’ve got excellent hearing and smell tho, so I guess it’s not the worst thing
Do you have gray eyes?
Human skin is almost like an eye that can "see" infrared. But we see it by feeling the heat.
That's a great way to think about it
Infrared is not heat. It's a common misconception. It's a byproduct of heat. And can cause heat. All hot objects exhibit blackbody radiation, and if they become sufficiently hot, the emitted photons get more energetic and can glow from red to white to blue and a little bit beyond (see: ultraviolet catastrophe). The thing is that infrared doesn't necessarily have to come from a high temperature source. It can be reflected by a reflective surface, or simply emitted by an LED in a TV remote. Of course, a remote LED does produce a little bit of heat in order to radiate a lot of infrared, but an electric heater produces so much more heat than that, comparatively. That's why the skin acting as an eye analogy is flawed. Some of it also has something to do with persistence of vision. Also, in astronomy the vast majority of observed infrared comes from hot objects, and that's where that parallel comes from.
At the root of all our senses thry are one organ so I would agree that what your skin senses Your "I" see's n experience
@@neoqueto I'm going to nitpick the nitpick here. (Yes, I know what blackbody radiation is)
We *perceive* infrared radiation as heat. In that regard, our skin works as a bolometer; an instrument that measures infrared radiation by the side effects of heating the sensor. Really strong visible light can feel hot, too. But its blinding brightness will dominate our perception of it.
Human skin also reacts to Ultraviolet. It burns with over-exposure.
Joe: “you were prob taught the 3 primary colors are red, green, and blue”
Me: no, they def said Red Yellow & Blue. Green is a Secondary color.
Yes, I was taught the same as you were, wondered where Joe got his info. In the practical sense, yellow & blue mix to create green; thus the primary colors are blue & yellow (& red). These three primary colors were classified as primary because they cannot be created by mixing other colors. What was confusing for me about what we were taught in public school was that black was classified as the absence of color while white was considered the combination of all colors. This black/white color theory was also taught in books on color for artists. But with paints at least, black can be created by mixing of all colors while white cannot be made by mixing colors & is the absence of color.
AK
I was taught that too. I'm an artist as well, it's blue, yellow, red.
Haha that's what I came down here for.
Both are correct. I know, I know! It hurts the brain. For painting (art class etc) the primary colors are red blue yellow indeed. Which is why you were taught this at school
But for LIGHT, the primary colors are red, green, blue (hence RGB). Which is why you were also correctly taught that black is the ABSENCE of light (not paint) and why white is the combination of all of these.
Hope that helps
@@janegarner9169 I was taught just the opposite--black was all color because it absorbed and white because it refracted all color...gotta love it...
The CMYK acronym stands for Cyan, Magenta, Yellow, and Key: those are the colours used in the printing process. A printing press uses dots of ink to make up the image from these four colours. 'Key' actually means black(for the record other colours have been use, so K is a catch all placeholder). It's called Key because it's the main colour used to determine the image outcome. Great channel thanks for all your hard work...
I thought it was K because that letter isn't the start of any other color.
And I thought on RGB blue is already taken "B" so on CMYK BlacK is represented by not first latter B but instead of last latter K.

To all the tetrachromats out there. Was the dress blue/black or white/gold?
They wouldn't be able to tell unless they saw it in person, the display only gives off RGB~
The perception of it is still vulnerable to the same pre conceived notions that anyone else has. Not having a full compliment of light queues, and the colors are muted by being on a monitor after being recorded on a tri color camera, and compressed with algorithms that are optimized for tri color images. So it's still up to the personal prior experiences and if they are more used to bright or darker environments.
For me it flipped back and forth, favoring white and gold. It was really weird!
Cameras are RGB, and so are the screens you saw it on.
If tetrachromats really want to see what colors match and what don't, look at it through a computer screen or a phone screen. It will limit it to 3 color and will then make them see it like we all see it..
K is for black because it was the 'K'ey color that the other plates (CMY) were aligned to.
Indeed. Bonus fact: the word black used to mean something like bright or white.
that was clear as mud. what does it mean?
@@squirlmy just read a little about CMYK printing. They made a plate for every color. When the plates hit the paper, they need to be properly aligned. The black plate is the key they are all aligned to. When you get a Sunday comic and the colors are all askew, it is because those color plates are misaligned. It probably doesn't happen much these days because these are old printing techniques. This Wikipedia article has a great example of it. en.m.wikipedia.org/wiki/Printing_registration

I recently read a short story called Seventh Sight, by Greg Egan. The main character is a teenager with a genetic vision problem. Fortunately he lives in a time where he, like his family members with the same condition, have optical implants that correct it. His synthetic retina is covered with artificial cone cells, but only about a third of them are used, the rest are there for redundancy. But these synthetic cone cells are programmable, and can be configured to pick up different wavelengths. The story is about a small group of kids who become aware of a firmware hack that reprograms the extra cells to pick up wavelengths outside of the visible spectrum.

I have excellent night vision - I only need a little bit of light to see. Back in college, the photography class had a dark room, and nobody else could see in it. But there was a tiny slit in the tarp covering one of the windows, and that was enough for me to see.
The drawback is that the light of day tends to be too bright to me. I like to joke that I'm part-vampire.
Imagine intergrating an infrared camera with neuralink
Me in 2040: That’s hot
crazy stuff but it needs to be implemented slowly or people gonna go insane
yep, its coming, and not just IR.
I never understood why humans didn't evolve to see IR since it would have been very useful to our old survival skills. (although IR and other wavelengths can be seen if bright enough via harmonics)
But neural link interfaces with the motor context. You would feel infrared. But we already have low resolution, capacity to do that because we feel heat.
@@sadface7457 yes but it could also interface with the visual cortex. Musk talks about being able to add other parts of the brain in the distant future
Even without neurolink, it would be easy to use a VR headset with a computer/camera programed to shift lower frequencies up and give you some control so you can adjust it to make sense of what you see. Say compress anything below a certain frequency and shift upwards. Same could be done shifting downwards for the UV end. Neurolink would simplify it in application, but we could have this now, with existing tech.

@ Nah your eyes just get dilated on LSD, so colors are more perceptive, bc your eyes are letting in more light. Colors seem more intense and such, but your not seeing a larger part of the spectrum. Just what you normally see intensified.

I have tetrachromacy, but I also inherited something from my paternal grandfather that allows me to see into the UV spectrum. He was also red/green colorblind, so I find it interesting that we both had this extra color of the rainbow while i was seeing more colors than "normal" and he was seeing fewer. I discovered this UV ability when I was in physics in university and we were measuring light wavelengths and I kept getting purple "wrong". The instructor took some extra time with me to test it and said I was seeing UV - if looking at a rainbow spectrum, it just looks like the purple gets really intense and extended. Rainbows are always a little lopsided to the blue/purple side. And being in a dark room with a black light is not as fun as it is for others.

Two wonders I''ve had for a while---
1-The overlap between red and yellow (orange) seems stronger than any other secondary-primary overlap. In fact it's the only one so wide and clearly distinguishable as a separate colour when viewing the spectrum.
2-Blue seems to somehow be overlapping with a red we can't see, and instead of magenta we see one closer to blue we call violet.
It's as if the overlap between yellow and red was made bigger while part of the overlap between blue and green was removed to make space. Perhaps we used to see magenta in the spectrum but for some reason it became more important to identify differences in orange and we evolved as such. . . But still maintained the ability too perceive magenta.
I learned similar differences occur in our ability to smell. Some friends and I were walking thru the Rhododendron Garden in Portland Oregon, and we found that the same flower might smell good, bad, or not at all to different people. And the floral scents detected were different as well. I don't know if this has been researched from genetic, perceptual, or biophysical perspectives.
Listen to this Dick we are talking about eye sight and he is telling us how far away he can smell shit go figure.
A good example is the smell/taste of coriander/cilantro. Our office is divided.
I love Durian! Most people are repulsed by its smell and taste, but it's the sweetest tasting thing I've ever encountered.
It's similar to genetic differences between people causing Cilantro or Brussel Sprouts to taste awful to a portion of the population. My Dad likes Cilantro. To me, it literally smells like a stink bug. We had a couple of summers where the stink bugs were bad, and around that time, I decided to buy fresh Cilantro to try it. I spent a couple of minutes searching through the bag, because I was convinced a stink bug got into the bag. It turned out to be the Cilantro. I understand it tastes good to some, and I believe it, but the smallest amount in my food, causes it to taste absolutely terrible.
Like or dislike for the taste of brussel sprouts has been proven to be a genetic difference.
It's not about the sprouts. They are just the indicator.
It's about the taste receptor.

The "K" is for Kuroi, the Japanese word for black.
"K" is for "Key", not 黒い. This is because even though the combination of Cyan, Magenta and Yellow should produce black upon combination in reality the pigments produce a muddy greenish mess, so a key-line made out of black ink allows the image to have better contrast.
I assumed they used K for black because B was already used in RGB for blue. If you're familiar with RBG then CMYB might seem like it stands for Cyan, Magenta, Yellow and Blue. So they used K instead. Just my assumption without really thinking much about it or looking it up :)
K is used to eliminate the confusion because B is already used in Blue, so they came up with a unique letter used in the last letter of black instead of the first letter.

They were in school. Apparently there are others, depending on what you do for a living/as a hobby.
Makes me angry at how little we're actually taught in public school. (Not just the primary colors, mind you. For instance, did you know there's a special court for victims of vaccine damage? Where was this Federal Claims Court when we learned all about the 3 branches of government in the US? Were you taught about Public Law 102-14 & all its implications? Strange, since it became law in 1991 under the title, *Education Day,* USA & is signed off on every year by every POTUS. What other laws require such dedication?)
Nope you are right! However there are two systems. RGB refers to light primaries (additive system)... Meaning a colour + colour = a brighter colour (I.e. our eyes, computer screens, etc)..
RYB refers to the original primaries or pigment primaries (subtractive system) meaning a colour + a colour = a darker colour (I.e. Paint, etc. )
I attended DOD schools except 7th, 8th, 9th and 12th. Fortunately, I was taught about RYB, RBG and CMY before attending public schools during those years.

I received an honour in colour, the part of the test I gained the honour was colour matching with my eyes then mixing the same colour not knowing the original mix and I had to account for the drying process which made the colour lighter when it was dry paint as opposed to wet paint (darker)

"I can see and seperate the colours that make the colour I'm looking at in my head..

@@Nitephall be careful what you wish for.
FYI, printers use "K" from the old days when printing machines only printed one colour at a time. If you started printing CM or Y before printing black, you would have trouble fitting the black to the colours as they might have been 'out of register' since those colours usually have to fit to the black but not always to each other. Imagine black keyline text filled with a mixture of colours, the colours would be hard to align to each other with no black outlines to fit to. So they printed the Black first and they called it "Key". Also, they didn't label the separations with B, as that may have been confused with blue or another spot colour. (This began in the days of chromolithography when they may have used several 'spot' colours as well as cmy). Also, the 'Key' was not always black! Sometimes it was a brown or whatever when they weren't printing cmyk jobs. Bottom line is that the principal colour that the others would be fitted to was called "Key" and was always printed first and for the last hundred years or so, almost every printing job has had black as the primary for alignment, so 'K' has stuck!
The "cat facts" got me. I never knew all calicos were female.
_The more you know..._ 🌈🎶
not completely correct i believe... male calicos do exist there just really rare, about 1 in 3000 apparently, and also their worth up to $2000
True. They are very rare for the same reason color blind women are very rare. Edit: Or the opposite reason, depending how you look at it.
I learnt about it in a genetics course, which went pretty deep into how and why it happens... I don't remember very much about it any longer, but it was really fascinating stuff!
And the very rare male cats are sterile.
The occurrence of male calico cats is theoretically impossible but they do happen.. Ordinarily, male cats have XY sex chromosomes, while females have XX. The X chromosomes carry the genes for coat colors. Therefore, female cats inherit their coat color from both their queens (XX) and their toms (XY). Male calicos are rare: Only one out of every 3,000 calico cats is male, according to a study by the College of Veterinary Medicine at the University of Missouri. The gene that governs how the orange color in cats displays is on the X chromosome. Females can be orange tabby, calico or tortoiseshell.
Why K? Because B was already taken in the RGB scheme, Red, Green & Blue ;-)
Blac-K
why not N for noir/negro
Black is listed in the CMYK scheme as "Key." Hence the K.
Why "Key?"
Think of it as the "master color" (yes, black, not white, lmao you Nazis) that you'd get by combining the other three colors together. It's the key color.
Kit Marcos lmao you nazis
Yeah, but the question is "Why K" not "Why not B"
Black is added in CMYK Because inks aren't perfect, and mixing CM and Y together just creates a muddy brown.
Not to mention in that a huge number of documents coming off a printing press, black is the most common (or only) color. No need to use 3x the ink.
it's also for saving on ink, instead of using more C,M or Y ink to make it darker, you use the black ink

I thought CMYK was fashion shop chain.
On a computer screen, black is ABSENCE of color. If you want black, just DON"T light up the pixels.
Great video. I love thinking about these types of subjects.

I found out that a lot of infrared LEDs used in remotes emit a bit of red frequency peak. So that is what I see. I can see pure infrared only of it is very strong like the ones used in cameras.
I just tried it and I can definitely see the red light if i shine it at my eyes right. I think we all can

"It's always interesting when you find out that somebody else can perceive something that you can't."
Only if they have a point of reference to relate to your perception. Without a relatable point of reference, descriptions of a new sense have difficulty connecting. I've dealt with that for almost a decade now.

What about Scott Manley?
Late to the party but, I’m a photographer who shoots primarily in IR/UV. I utilize a lot of false color IR which mixes some IR into the visible light spectrum (VLS) and creates red/magenta vegetation. The camera is actually converted to “full spectrum” and when you white balance on something neutral the imagery is washed out with a pink tint. Super interesting.
Yes I do to. The pink hue is because there is an abundance of NIR light hitting the sensor. There is a lot more IR light coming from the sun than visible or UV. Vegetation is super reflective to NIR light (a lot of things are) therefore it appears as monochromatic or the same color. Depends on which filters you use of course.
Colorblind. I have to keep reminding people that the "green" wire looks exactly like the "red" wire to me. Yea, don't ask me if a line is hot unless it has a label on it. ⚡😎⚡
Where are you from? What is the wiring coding over there? In Europe we have, brown for live, black for switched, blue for neutral, yellow/green for earth.
kids get taught: red, blue, and yellow.
no till you find out about 'cones and rods' does that get corrected to green, blue, and red.
Huh?
True but some painters still go by that. You also have value i.e. How dark something is, and you really cannot mix a light yellow. Yet red is more saturated, more useful, and blue is darker than the cyans...it would be a greener blue and a purpler red too so its just a renaming sometimes,or bc those pigments are expensive, or translucent. But yes its technically incorrect. Except until you make a paint set. So is the concept of getting all colours from 3 paints because you can find a pigment more saturated, or a different value to the mix of cmyk or rby.
Red, blue , and yellow are correct for mixing pigments. RGB is correct for mixing light. CMYK is correct for printing since the 4 color process doesn't mix the colors. They are individual tiny dots carefully aligned to trick your brain. ( Although, one might argue that the brain isn't really tricked, sInce it is able to put all that information together instantaneously!😂)
Great video as usual.....I had diabetes from 18 yrs old to 40. At 40 I removed one food from my diet and my glucose levels dropped drastically and most of my symptoms went away. Shortly after I needed glasses. Then my glasses wouldn't work anymore so I bought stronger glasses until the 3.5x weren't helping me see. I went for a job interview at Bell and I failed the eye test and he told me that I was color blind. All I could see was different shades of grey and extremely blurry. Years later I checked my glucose levels expecting a 5.6 but I got a reading of 3.2. Didnt know what low blood sugar meant but I did not associate it with my blindness. I then replaced beer with energy drinks ( which I usually never consumed ) and my glucose levels began to move up near the 5.6 again. 6 months later I noticed a slight change in my eyesight. A year later my eyes improved further where I didnt need glasses anymore but they were not perfect because I still had problems with low light conditions. It's now 2 and a half years since I began drinking the energy drinks and my eyes are almost perfect again and I can distinguish color again. I beat diabetes Glycemia and blindness without a pill or medical doctor. After my eyes came back I noticed I was able to perceive invisible things like wind and figured out the inner workings of a savonius verticle axis wind turbine using my perception and was able to get a savonius turbine to spin at 32X the speed of the wind when they usually spin at 1X. Diabetes does NOT effect your eyesight but the opposite of diabetes Glycemia does. Diabetics who loose there eyesight is not due to high glucose levels but over medication of insulin which drops your sugar levels way too low which causes blindness and color blindness. I hope this helped. Joe did I mention great video as usual.
Crazy Contraptions so what’s the secret? What is the one food you replaced that brought glucose down? Why not just say. Or maybe it was beer. I am confused.
@@grantdouglas8523 The one food that dropped my glucose levels was sodium nitrate.
Anything that gets you stonned such as beer weed hard drugs sleeping pills pain killers do so by lowering your glucose levels and that's what gives you the buzz. Sugar and carbs increase your glucose levels and are our fuel for our cells. Sodium nitrate does not affect present glucose levels but slowly increases fasting glucose levels and over time the increase in fasting glucose levels adds up and diabetes sets in. By removing this poison out of my food my fasting glucose levels dropped from a 20 to a 3.2 .When I removed the beer glucose levels went up. When I added sugar glucose levels moved up to a 5.6 where it is now. I hope this helped if need anymore info please dont hesitate to ask.
@@frankgiancola7
Sodium Nitrate Vs. Sodium Nitrite.
Did you also remove sodium nitrite also ?
What about salt ?
Plus there are more naturally occurring nitrates in a kale salad than a pound of bacon, how can that be bad?
Thanks
@@rainerrain9689 Sodium nitrate and sodium nitrite both raise your sugar levels over time. They are both equally bad for glucose levels. After consuming them my glucose would not change and that's why it was so hard to pick out which food was causing the problem. Over time nitrates increase your fasting glucose levels a tiny bit at a time where it is not noticeable from day to day but over a span of a week or even a month those tiny increases in glucose levels are noticeable and as years go on glucose levels millimeter their way up until symptoms began to appear. At 18 years old I began getting restless and my feet began to get itchy and I began to get edgy. Then my appetite slowly began to increase. As the years went on all the symptoms worsened until I couldn't sleep anymore at all. My appetite was ferocious. I would eat 5 times before lunch time and still be hungry. My mouth was really dry and my mood was worsening. My feet were like ice and really itchy. Some days I would walk with a limp. I was always cold and my hair looked like steel wool. For years I was removing one food at a time over a weeks period and did not notice any changes until I removed the salami sandwiches hot dogs and bacon and this was a few months before I turned 40. I had a welt on my foot for a few months that wouldn't heal and I thought I would loose my right foot. After removing those foods my glucose levels plummeted from the normal 20 reading I was getting. My welt went away and feet came back to life. My mood was really good after that. My ferocious appetite dwindled to an appetite of a bird. A month later I ran for the first time 10 km and still do today without even breaking a sweat and I'm 55 years old. The only symptom that remained was my restlessness and my eyes were still good. A few years later thinking my glucose problems were solved my eyes deteriorated from perfect to blind. I then checked my glucose levels from a freind who had a glucose meter and It red 3.2. Then i increased my sugar levels by consuming energy drinks and i quit drinking because drinking and low blood sugar dont mix as i found out. I would have one beer and i was completely drunk. It's been 2.5 years since i had a drink nor do I crave one. In the last 6 months my last symptom went away and now I am able to sleep again. Sea salt is good for you and table salt has tiny grains of sand in it which scar your arteries as they circulate which create plaque on the artery walls. Most of the veggies I eat are from my garden and I DONT use sodium nitrate as a fertilizer as most farmers do. If farmers dont follow the guidelines put place by the govt. Then they dont receive any funding so that's why almost all our veggies have nitrates in them. I hope this helped if you need any more info dont hesitate to ask because there is so much I learned about my health over the past years which I did not read from anywhere and are from my experiences with diabetes and glycemia. Diabetes does not come from over sugar consumption but from sodium nitrate. Over sugar consumption lowers your fasting glucose levels as your body reacts to the spikes in sugar. Blindness does come from diabetes but it comes from glycemia. I hope this helped.
In the mid-'90s, my profession as a commercial photofinisher, transitioned from analog and optical to digital and optical. Here's how the RGB/CMYK difference was explained to me. (This was mostly to address the printing process - think of a darkroom enlarger used to expose photographic paper vs an ink-filled printer used to transfer an image onto office paper.)
RGB is the visible light model. It's how our eyes see colors of light.
CMYK is the reflective light model. It's how our eyes see colors of light reflected off of objects.
0% of RG & B in light = black
100% of CM & Y reflecting from paper falls short of black due to ambient light dirtying it up (it's a dark grey). Black ink is added to compensate for this.
These are opposite spectrums:
Red is opposite Cyan in the spectrum
Magenta is opposite Green in the spectrum
Yellow is opposite Blue in the spectrum
Black is called K to avoid confusion with Blue and the K is referring to the K at the end of the name.
(edit - after posting this, I did some internet searching and found that K stands for Key, as in the Key Plate in a 4-color printing process.)
The CMB is very diffuse, like near-absolute zero levels of energy. So I doubt microwaves would light up the night. At least not from that alone. You'd be able to spot some of the brighter neutron stars, and that alone makes it worth it.
I think the wifi and other communication bands would be much brighter, at least in a populated area.
It is semi diffuse but it does provide a hiss for radio telescopes attuned to that frequency. In fact the CMB was discovered by a telescope being set up to pick up microwaves and when they started looking at the data there was a hiss or static they couldn't get rid of. So it is significant, but I also do think manmade low frequency radiation would drown pretty much everything else at that frequency range out.
Agree.
I believe the "temperature" of the CMB is around 2.7 degrees Kelvin.
Thats why you use LEDs to grow!
Very low heat production.
Well this, plus better overall efficiency :-D
same thing
I think you need some UV or IR light to grow them, but I might be wrong. LED's have a very narrow band of light usually.
"What If You Can See Every Wavelength Of The Electromagnetic Spectrum"
Sponsored in part by Jimmy Dean Sausages
Your comments about seeing ultraviolet caught my attention because I had my lenses replaced several years ago because of cataracts and for about a week after that everything had a pinkish hue to it. Occasionally I still see it if I've been in REALLY bright sunlight for more than a couple minutes then go inside or somewhere not as well lit.
Star Trek: The Next Generation tried to simulate this by giving moments of Geordi La Forge's vision.
Lt. Data : 'how intriging'
It was for about a minute or two in one episode, until the computer was overwhelmed by the data stream.
[EDIT] Sorry, no, there was another episode, where Geordi was 'brainwashed' to be used as an assassin to kill the Klingon Chancellor.
(Yes, I am a total Star Trek geek.)
Love this episode. Please talk more about this subject and tetrachromacy.
So, I'm stereo blind which means I can't see 3D. 3D movies look pretty flat to me. I have a hard time with depth perception. That might be worth talking about.
There was a professor that had too until he went and saw a 3D movie. The 3D movie somehow unlocked the ability for him to have depth perception.
Kopak, are you a cyclops? That could be the cause of your affliction.
@@themikeshow I think if one eye is just slightly off it would create it, so they don't fully line up. I've had that at times, or times where I get hyper 3d....not sure which, it's a bit distracting where like a bush is suddenly very 3d, but never been able to for sure tell, it's more like seeing in perspective. But not 100% sure again :> Just know that 3d movies or view master felt a bit different then what I usally see heh.
Thanks, I didn't know there was a name for this. I have the same issue, however, it seems to have developed after I turned 45.
How do you cope with stairs? I did an experience experiment in my ASL class for the blind/deaf unit, I had a small hole of sight and my depth perception caused me to have serious issues with going up and down the stairs...
The reason why we see magenta is that our brain adds the two colors, the same with the other combinations. It not that we see in between those colors, it is our brain combines the colors. By the way I am a photographer. Back when I was growing up the three primary colors for pigment were red, yellow, and blue. Printers used those colors to print pictures using those along with black. Color photos in magazine needed the photos to be taken with "transparency" film (like slide film). However that must have changed before the 1990's, because when I shot covers for a magazine called "Media ByPass", they specified negative film. That may or may not been because they may have just sent prints. While printers used R,Y,B, photographers always used CYMK when in the darkroom. Curious.
I've noticed tones seem different it I look at things with one eye of the other. One sees things warmer and the other one colder.
I've noticed the same thing. Mostly on really bright days though. Red will seem a bit faded for my right eye compared to my left. Most of the time I can't tell any difference though.
Im in my 30s and i just noticed this the other day when i was staring at the asphalt. One eye is "cold" and the other "warm"..its very annoying now that im aware of it lol
it happens to me too but i know whats causing it... its when the sun only hits one of my eyes and the eye it hits is colder and the other one warmer.
glad im not the only one that this happens to.
When my son was about 3, I noticed he kept shutting one eye and then the other. He explained he could see the colour blue nice and bright in one eye, but not in the other.
This was indoors and so nothing to do with looking at the sun or at bright lights bleaching the eye, because he says it's still the same years later.
So I'm guessing some people have uneven numbers of cones in the eyes, or even one eye that has a total absence of one or more cone type?
Infrared cameras are also used for search&rescue, espcially in the north.
border patrol mostly. but not uncommon in other branches
Color is a muddy issue. Pigments and "color" are different. Colored light does one thing. Pigments do another.
Plus structured color (like bird feathers sometimes have) which appear to change color at different angles of light reflection.
I’ve recently wondered about this. It would be very interesting. I really liked your comment about us already doing this. People don’t think we are evolving but our technological advances are us evolving. Our technology are a huge part of us now so we shouldn’t discount that. Thanks for sharing
My three older brothers and I used to point an old television remote into our eyes as a kids and I definitely used to see a purpley red flash although they did not, however I can confirm that I no longer see this with repeated tests as an adult.
Im assuming either the infrared sensitivity is prone to degradation as we age, or I and all of my brothers permanently damaged our eyeballs....😅
I think what’s more likely is old IR LEDs would also give off a little bit of visible purple light too. Newer LEDs are probably better optimised.
Well i have three older brothers who also tried and never saw anything, being the youngest sibling i have always assumed that kids just have better eyesight, if you think about it seeing in infrared as children could have boosted our survival rate quite significantly a couple thousand years ago if we got even the faintest glow of predators before an attack.
Not to mention 700nm is red that we can see already, infrared sits literally just after that at 750 nm to 1 mm so its actually pretty likley that we can see atleast some of the spectrum, especially as children before our eyes begin to degrade.

Great video. I was hoping you would talk about the biological requirements of being able to see those other wavelengths. Like how we would need to have gigantic eyes in order to be able to see the longer wavelengths of radio waves.
I was hoping for this too. Also detecting higher frequencies would require subatomic retinas, perhaps even less within the realm of possibility.
Radio wave observatories cover acres.
I JUST FOUND OUT IM A TETRACHROMATIC!!!!! THIS EXPLAINS SO MUCH!!!! I was really confused at how ANYONE could see that dress as being gold or w/e instead of blue (optical illusion that because a huge internet thing a few years ago)
EDIT: oh nvm, I just found that computer screens can't (apparently) produce the light needed to test it.
Also they are all female..
On the topic of being able to see infrared. Did you know that if you let your eyes adjust to the dark long enough, then look at the IR LED on the front of your TV remote, you can ever so slightly see a dim brownish-red light flashing. Not sure if everyone can see it but I could, it's just very dim though.
You can also see it through your phone camera.
OH! an it can blind you because your iris won't adjust to filter out light intensity that it can't see.
So if you stared into an ir spotlight it would be dark and painless but you'd go blind without noticing it.
Interesting. I know most digital cameras can see IR.
They have an IR filter, but it's almost never fully effective, and the sensor can pick up near IR...
On another note, the human retina can detect UV light, but the lens filters it out. (for good reason, since UV light damages the retina)
The things described by people that have had something happen to their lenses is... Interesting. (usually this is caused by cataract surgery)
@@foolapprentice3321 I mean maybe if you stared at it non stop for like 10 mins straight an inch from your eye. But it won't do any lasting harm to hold the button in for a few seconds and look at it. Think about all these "ghost" TV shows and their night vision cameras in tight spaces looking at the hosts reaction, they have a far more powerful IR light shining straight in their dilated iris and they're fine. A TV remote won't do you any harm mate.
@@thecapacitor1395 read closer
Omg I wonder about this all the time... one of my favorite ideas for cybernetics is an eye that can see the entire spectrum... Sort of like Geordi
Our brain might be overwhelmed by all that new information , we'll probably need a neuralink or something better to add extra layer of processing power to our brain.
Yeah, I don't think our visual cortex is built for that.
But... Certainly it might learn to adapt a little.
Probably doesn't have the 'processing power' to deal with that much information though.
@@KuraIthys oh I would like to think that if say, we could hijack and through training add some extra functionality to the focusing systems of our eyes we could use that to move through the ranges of spectrum perception available on whatever eye "prosthesis" used.
wolvenar ... or just as was described in a ST:NG episode, Jordi shifts his attention around the spectrum. He only bothers with IR one moment, then UV the next, x-ray the next. Just like we only really concentrate on the centre of our vision and hardly any time on the periphery.

I do have a few weird things with my senses, such as the fact that even though I have trouble seeing distance, I can see better than most people the differences in color, and I have control over what I see and how, like certain loading circles I can make spin the opposite direction. I also can get true tulle vision, were everything but what I am focused on becomes part of my peripheral vision. I can focus on things in my peripheral vision while still looking strait, like in a mirror I can look in a direction and focus on my eyes still looking in that direction. Other senses are weird as well, with my hearing being shifted slightly to higher wavelengths than normal people, but not hearing all low wavelength sounds. My smell and taste are good enough that I can smell/taste some things once and be able to tell later that a different smell/taste is the same. What I smell I will also taste. I can also taste metals by looking at them sometimes, such as looking at a rusty bumper I will taste iron. I have a pain tolerance that makes me not able to feel most high intensity pain but low intensity, or sharp, quick pains I will feel, like stubbing a toe. This includes exhaustion, were I if pull past the low exhaustion I will not feel tired after. I don't feel hunger at all, and only eat by checking the time. My vestibular sense are not perfect either, were I don't get motion sickness from any movment, not matter for how long or fast I am moving, which is mostly spinning.

Great animations, vision is so cool. Always wanted glasses that could see IR and UV. I do have microscopes and telescopes to see cool stuff too. Or glasses to see even more RED as I'm red green color blind and am curious what normal people are seeing.

Lol. There are many different whites. Some involve tint, others shading.
K stands for key. Black is not part of the chrominance layers but is rather a luminance layer called key plate in the print industry. You have the same in video signals. The B&W image is the luminance layer. And the chrominance is added on top of it with separate channels for each color or in a single chrominance signal with less resolution (color definition does not need to be very precise). In the eye the rods see the luminance. The cones see the chrominance. There are 3 times more rods that specific cones.

@@HappyFlapps What? O.o
Okay, without first even watching the video, if you could see every wavelength in the spectrum, my guess is that you would become unrecoverably insane in the first 30 minutes.
If we augment only eyes but not the brain's ability to process those signals, yup. Not insane, but we'd just go with eyes closed due to the "noise". Eye is just the collector of information - it is the easiest thing to do in the whole chain. The problem is always the processor part. Think for instance the radio-telescopes. Shitloads of data... that would be useless unless we had clusters of supercomputers working on them. Then it's no problem. Same with this - it all depends on the brain. If it remains the same, sure, crazy it is. Even with visible light currently, too much of different wavelengths at the same time and our head hurts after a while.
But any broadening of the humanly visible spectrum will HAVE TO be accompanied with brain augmentation. If anything, brain needs to know what to do with those signals it receives. If you just convert the gathered signals and convert it in current brain capacity, it would not make any sense. It would just see more of the same colors.
And that's the thing, you can't think of a color you have not seen.
Brain is the key here, not the "eye".
@@Wustenfuchs109 It'd definitely change your perspective, but I'm guessing the brain as is could work it out to a point. Not if you are going full spectrum, but if you boosted the available wavelength data by 20-50% it could probably learn to deal. The colors aren't a big deal imo, the only reason you know to call a red thing red is because we all agreed on the name, see the Vsauce video "is your red the same as my red" or something like that, green and red strawberries on the thumbnail. Anyway, your perception is already weird when you learn about it.. the brain would probably say "that looks different" if the data allowed for it, and then render something. You'd never question it unless you could switch back and forth from having it or not.
Humans- visible light
Bees- UV light
Pit Viper- infrared
.....Strange world
It's not strange at all. Each organism evolved in its environment to have the type of senses that gave it the best advantages at reproducing in that environment (and thus passing on the genes that made them successful). Humans that could differentiate colour had a survival advantage, bees that can see certain flower markings enable pollination and also get food (and with the flowers that make themselves the most visibly attract also having a survival advantage, there is co-evolution) and pit-vipers that can track the heat of a warm-blooded mammalian rodent after having injected it with venom, thus taking its time to follow along and find the dying prey, it also had a survival advantage.
