The Color White Does NOT Exist
HTML-код
- Опубликовано: 8 сен 2024
- Color is a property that belongs to light (i.e. electromagnetic waves). We only think objects are colored because of the light they reflect and scatter. In fact, some of the colors you see are an illusion created by your eyes and brain. What colors are real and which ones are fake? Let's find out.

Art teacher here. I've tried to explain this to kids with great difficulty before. Now all I have to do is show them this video.
No, no, no! Explain to them that there are different colors and different experiences with colors, not that a red apple is actually not red and does not even have a color, and that white is not a color. Teach them some good science about light, enough to make the work of a visual artist easier.
Can't quickly think of an example, but I've seen work of very creative artists that use this knowledge of colours, and we see it in a certain way until it is pointed out what they did.
@@AlleyKatt Every artist, at least since the renaissance, has known about primary and secondary colors even if they did not know about the light sensors in our eyes. I am pretty sure that no artist has ever thought "white is not a color, the red apple in fact has no color either, I will use this in my painting". I would like to play with holograms and lasers to make images that different people see differently, but I would still be using objects that have a property called "color", and I would still be using combinations of different wavelengths that are, by definition and by physics and by anatomy, a color.
There is a lot of physics and biology and optics that you can learn, much more than what was presented poorly here, and it can be used by artists and scientists in several ways, but just redefining words is not the way.
@@andresvillarreal9271 So we should NOT tell kids the reality of physics and biology? In which way this knowledge will prevent them from being good visual artists? I honestly don't understand your reasoning...
@k1ry4n... I’m in agreement with you..it’s not bunk science..
As a painter/digital artist this video is pure gold. We see and think about this sort of stuff all the time and still STILL I hadn't connected the dots for how the brain just makes extra "colours/detection labels' for stuff like magenta and white. That was awesome!!
I know interior designers have to consider lighting too when choosing colors for a room. It's an important thing to know!
@@ScienceAsylum indeed I'm sure it is

Question: What color is your cat?
Answer: It has no color.
The best way to end a discussion.
I don't have a cat
FYI: The audio from 4:15 to 4:30 is intentional. You never know when my mind vortex will appear. We were overdue, I think.
That being said, I do glaze over a lot of biology there and, no matter how disappointed you think you are about it, my (biologist) wife is _more_ disappointed. She's happy to have your support though 👍 EDIT: If you want more details about the biochem, Steve Mould did a whole video about it: ruclips.net/video/dvovtbLGaUw/видео.html
HOW WHITE LED SHOW WHITE COLOR ????
@@samarwahid7313 There are tri-colour leds, usually with each of the monochromatic RGB individually controllable, but the normal method is to take an ultraviolet emitting LED and put a mixed "phosphor" on top that converts the light to a wide band of red to blue.
Then perhaps your wife can make a 2nd episode on the subject you so graciously glazed over? ;)
@John Doe) Watch the video again and you will find he said that. Now pay attention, Johnny!
Does any color really exist in reality?
Man, I knew all of this, and yet presented by you it just blows my mind anyway.
This channel is among my most favorite-est ones. I'm glad this exists.
edit: ...as far as I can tell, anyway.
Lol
"What's your favorite color?"
"White"
"Oh that doesn't exist"
"Wtf"
6:18
Reminds me of by Vsauce
Yeah
And that title is equally clickbaity and wrong. Color is by definition a perception, *not* a physical property of light. His statement at 2:37 is only half true: technically, neither objects *nor* light have color. Even Sir Isaac Newton already knew this and wrote "Indeed rays [of light], properly expressed, are not coloured. In them there is nothing else than a certain power or disposition to stir up a sensation of this or that colour."
On the physical side, you have reflection or emission spectra, but not color. Colors are a perception, and therefore are subjective and depend on context. Meaning that physically identical spectra can be perceived as different colors. There are many optical "illusions" that demonstrate this, such as the checker shadow illusion, or that infamous black/blue white/gold dress. And conversely, different physical spectra can be perceived as the same color. Yellow is a simple example for that (spectral i.e. single wavelength yellow vs. yellow made from red + green - physically different, but perceptually identical, and therefore the same color).
Yeah! Great summary indeed!
@@TheBytegeist ...BORING 💩
@@TheBytegeist I think he went with another definition not from that sense but as in the spectrum of visible light. Either way, it's not worth debating as it is an equivocation fallacy, and yes, the title is clickbaity in a way.
"Ever going to look at color the same way again?" Nice try, but how can I look at something that doesn't exist?
Good answer.
1:25 : *_Okay, I suppose I could e-LAB-orate._*
Call this man a Doctor, He's sick!
amazing info!
@@adama7752 Which man am I calling a doctor?
My man, I recently got interested in painting which led me to be interested in colour mixing which led me to wondering what's going on with light, and you have proved to be an excellent resource in this rabbit hole. Your whole series on Optics and Light has been incredibly valuable to my understanding. You are a fantastic educator and I cannot thank you enough for what you do.
Thanks. That's always nice to hear.
so white people are actually light people.
Lets take a moment to appreciate the art skills of Nick.
When you have watched too many physics videos and read momentum instead of moment, you know the time has come...
@@MsSonali1980 😂😂
Thanks, Nick. You've refined a misconception I've maintained for 60 years.
(And I understood it all, too. You're usually a little advanced for me.)
Really?, he usually dumbs down the difficult topics (but without misconceptions), so people can understand it better.
@@martiddy Well, he might, but that doesn't mean he can penetrate my region of the dumb-to-bright spectrum. It's pretty dense down here.
Here I am just minding my own and enjoying an amazing video by the science asylum when all of a sudden I see Nick lucid in a white T-shirt in a shower. 😲🤨😀😂😂🤣🤣 LMAO !!!
didn't you learn anything? white t-shirts do not exist!
That image threw me for a while...
Lolololololol
@@wheeliekidbp NO ! LOLOLOLOLOLOL !!
No you didn't - it was just a clone. :)
3:36 lmao! Things you just can't unsee
Well, I'd rather see a wet t-shirt on nick than a wet t-shirt on Rosie O'Donnell.
I always look forward to seeing notifications from your channel.
Try looking backwards ...
Today I learned that magenta isn't a spectral color. All this time, I thought it was a spectral color with a hue angle of 300°. I learn something new every time I watch this channel. Thanks, Nick!
I think I heard that the red cones have a second response peak at wavelengths shorter than the blue cones' peak (they fire at "violet", but not at the longer wavelengths of indigo blue), which is why the spectrum looks like it maps onto a color wheel despite not looping.
And as Nick described, an RGB display has three colored lights in each pixel so those mostly aren't spectral colors, either.
@@awfuldynne huh....
@@awfuldynne I always wondered why the color wheel loops
6:19 Hey Vsauce, Michael here!
This was so perfect mix of biology and physics! I love it!
3:36 🤣🤣🤣🤣 I almost died laughing. You rock nick 👍
Well don't die watching funny moments , how would it feel when you're laughing hard and suddenly you die 😂
Sexy nipples
I was laughing about the "mixed signals" and that he fell asleep during the biology monologue... :D
4:44 Have we discovered that there are only these three receptors in our eyes before we created pixels on the screens?
I would say wavelength is a property of light. Color is an emergent property of consciousness. Although color does correlate with wavelength often, that's not a requirement. From that standpoint the color white or magenta is just as valid as the color red.
That seems fair. Dark red and bright red are just different preceived magnitudes of the same wavelength, identified as distinct colors from one another. And pale yellow is what happens when our eyes get the same recipe as plain yellow, with a little bit of blue in the mix. Of course, if we strip value (or brightness) and saturation out of the mix, we're left with just hues. Which almost correspond to wavelengths, except for that dastardly magenta.
So then, can we say that since color is not a property of light, objects _can_ have color? I guess we still have to say that they can't, since, as demonstrated in the video, the color of an object is perceived differently depending on the light that it is exposed to. And that goes outside of the visible spectrum, even. Something that appears to be mostly white in visible light may emit bright blue light when exposed to ultraviolet light. Is it blue when that is happening? Is it sill blue if we're not looking at it?
So yeah, I guess color is not a property of matter or of light. Colors are purely the product of perception. Or.... frame of reference?
@@tom_something Yep, I would say color is purely perception. For instance people will tend to see flashes of colors in a sensory deprivation tank, or on hallucinogenic drugs. There need not be matter nor light in order to perceive color (although these cases are the outliers to our day to day experiences).
@@iamamcnea There's a sort of color theory whereby the input from our three cone types then goes through an intermediate processing step. In this step, there's sort of an x-y plot. One axis goes from blue to yellow. The other axis, some say it goes from green to red, others say it goes from green to magenta. And the midpoint on each scale is basically an absence of color. So there's not really a way for us to perceive bluish yellow or greenish red. They're not colors, simply because our brains decided not to make them into colors.
It could have been a blue-to-green scale and a red-to-yellow scale instead, but it isn't. We just... didn't do that.
3:36
My wife: "Honey, why are you waving a dollar bill at the computer?"
Literally just talked color and light with my physics class. Students were in awe in learning the sun is white. I must show them this video!! Thank you.
Brilliant video.
You covered: the light spectrum (Physics), the human brain (Biology), the RGB distribution (Computer Science) and the LCD screen design (Engineering aka Applied physics).
And that shower scene...LOL!
Nick, thank you so much for the examples. It makes complex subjects like this a breeze for the layman. I fully support your work.
What’s crazy is he answered my question but I can’t stop watching. Bruh keeps it concise for everyone to understand.
3:35
You just earned a like.
Well chosen T-shirt! There's "Pink" (obviously), the album title including "Dark", and a song title on the album, "Any Colour You Like".
Great video as always :)
This would also be a nice place to explain how color blindness works and how the color blind curing glasses work :) All it takes is few changes on the cones sensitivity graph :)
Crazy home experiment!
Just drop a little droplet of water on a white screen. It will behave like a lens and you will be able to see that RGB structure.
You can also try it with magenta(5:49), yellow(6:18) or any color you want!
I comment some times, but, Nick, you are--simply put--an inspiration.
You were born to be a teacher.
What I love about you (beyond the lessons) is your enthusiasm and your passion.
I'll leave it at that after I say one more thing:
I don't "see" anybody else in this production, but all those compliments go to you and all those who help you--particularly all those nice clones. ;)
One reason why I love your videos is because every time a question appears in my mind, you answer it a few seconds later.
One thing your LCD explanation missed: because each of the three primary colors actually stimulate all three cones (especially green), some combinations of "signals sent to the brain" are not possible to reproduce using an RGB LCD (the commonly cited one is "deep orange"). If you look at a chromaticity diagram, the colors reproducible using RGB are actually less than half the entire chart.
This is different from your "this is not actually yellow" because the actual and reproduced color are distinguishable, unlike "pure" vs. "red+green" yellow (this last fact is actually used in a color-blindness test called an "anomaloscope")
That's intriguing. Can you name some object that is 'deep orange' so i can make a photo of it and see the results in a LCD screen?
I am a bit late to the party... but You are true. Nick completely omitted "color gamut", even if it is a simple thing to explain - how our brain interprets the impulses from our eyes. With it it would be even more obvious that RGB cannot display "all colors" and that adding more colors isn't "a total and complete waste of your money". Heck, it is even clear from his speaking in the lines of "these three neural impulses are enough" (ignoring rod cells and its - albeit little - contribution to color perception), but clearly showing that e. g. "green" color in LCD screen fires the "red" cone also (and vice versa). Thus we cannot get many "rainbow" colors from RGB screen only.
Yeah, even white can be a combination of e. g. blue and "clean" yellow, that means only two colors.
Nick could even speak about materials not only reflecting a particular frequency (e. g. "it is yellow because yellow light gets reflected - its reflected light's frequency peaks at yellow"), but a combination thereof (e. g. "it can also be *perceived* yellow if its reflected light peaks at green and red frequency.." - or whatever color gamut is enabling).
I've had two bed sheets at home. They looked "blue" the same way (under sunlight, under fluorescent bulb). Still, there was difference. I shone at them with two LED light sources from different manufacturers. One looked the same blue, the other "changed" color to violet. (But both light sources' light cones looked the same when reflected off a white wall.) You cannot explain that without speaking of frequency combinations and gamut....
I like Nicks videos very much, but I think, he tried to keep it simple... and omitted important facts :(.
Your red phone becoming black under the green light was a eureka moment about how colours work....
Glad I could help 🤓
You made it possible for me to be happy to have a class! The happiness I get when seeing a new video is up amazes me every time! Bless you man!
Dictionaries are incomplete because there is no word in any dictionary which can describe your greatness! Spectacular!!thankssssss a lot!!!!!
Best explanation yet! I’ve been teaching this to amazed students fresh out of school, some of them fighting disbelief.
Thanks for the upload, I’ll be playing it to them.
Wdym "fighting disbelief"
man, you don't know how much sense you make with your clear understanding of the concepts and amazing presentation skills❤️
4:00 who else caught the typo?
Not me...
Me neither, apparently.
7:00 yeah but it still can't produce all the colours, since the colours lose their saturation when mixed. No display can be as vibrant as monochromatic light.
Good point.
Science is so great, but you Nick are also very good talking about it, and this is a thankfull combination
That’s fun when you understand that a thing is precisely not the color your eyes see. The green leaves of a three is any color but green. Green is what is “rejected” by those leaves, they’re not green themselves. I love this!
* Clicked on video *
* Liked it *
* Watched it *
* Loved it so much *
* I 're'liked the video *
Now that I'm finally caught up, I have some future suggestions:
Fine-Tuning
Entanglement (And specifically why we CAN'T use it to break Relativity.)
Some more pure information theory (As it's often relevant in physics)
What are Tensors?
What is Friction?
A video on the Pauli Exclusion Principle.
How do Lasers work(Related to the above.)
Monopoles
Some TOE candidate videos why their proponents favor them and why they are still in debate.
That's all I can think of off the top of my head.
Also I know you mostly do physics videos, (Because that's your area of study) But if you do other types of science videos maybe have some guest that are experts help you at least with the script if not be the guest star.
I'll consider these :-)
Useful stuff at 7:03
Awesome explanation.
Michael Murphy I feel like a stupid
I don't know how to appreciate your work. It's awesome.
I think that there should be a limit to the continuity of colour dimness maybe there is a defined amount-quantum of light which would be responsible for effective change in perception thus putting a limit to the number of maximum brightness levels per subpixel.
This may be similar to the case of the frame rate limit in our eyes.
Thank you a lot for forcing me to think about it.
@@Michael Murphy, I am a student and have recently qualified from high school and am looking for an undergraduate course in Computer science.
Once again thanks for bringing such a fruitful conversation.
Stay blessed Sir.
I so really need to show this to my students, who are studying the topic of light.
Thanks a million, Mr. Nick Lucid!
Correction: *Color does not exist.*
It's just how our brain interprets light.
Close, but color does exist. Like you said, color is what we call our interpretation of light. It would be more accurate to say that the white light doesn't exist.
Objects have color we should call it "Visible"
So, this video is discussing the difference between spectral color (a color that monochromatic light looks like), vs non-spectral colors. There are MANY more non-spectral colors that you see than purely spectral ones because the vast majority of objects do not simply reflect a single wavelength of light. Most (all?) objects reflect more than one wavelength, or reflect a range of wavelength, or there will be enough diffuse light that gets scattered that you perceive it as reflecting that wavelength. Things that appear "Metallic" such as gold and silver, are pretty much impossible for a computer screen to render because they are not made up of any combination of wavelengths by themselves. Since the objects reflect light in different ways depending on the angle of the light, you get a great deal of variation of color over the object, and it takes a very sophisticated simulation to accurately simulate this.
Just look at diagram of spectral colors and see how limited that is. Now, imagine every shade of grey from white to black. You can mix different spectral colors and shades of grey into millions and millions of combinations and derive WAY more combinations of color than spectral light. For example, 50% blue and 50% red gives a purple looking color. 100% blue and 100% red gives magenta (a very saturated color). You can get pink by mixing a reddish color with white. and brown by mixing an orange color with black or dark grey.
Oversaturated colors, such as something seeming whiter than white, are possible too, that your monitor has no ability to produce at all. Speaking of impossible colors your monitor can't product: you can mix red and greed, or blue and yellow, in ways that give the appearance of a brand new color, but you get a muddy color not even close to them by using your monitor or even paints.
Finally, I actually understood what he was talking about... I'm just a simple man
The fields of the universe are fascinating. They ARE the universe. How one field can basically handle almost infinite signals and almost infinite wavelengths at the same time is mind boggling.
Color is purely psychological - neither light nor objects have color, any more than certain vibrations 'actually sound like' anything - its all between the ears Nick.
Search on Google the definition of "color", looks like you don't know what exactly is "color".
@@marxk4rl Neither search engines nor dictionaries are academic sources. Try again Karl.
@@marxk4rl What do YOU think the definition of "color" is? I'm with IRL Server. Color isn't a physical property of light, it's a subjective perception.
Taking it a step further, color is merely an articial interpretation of waves used by our brains to make sense if the world. Blue can refer to a wavelength, but we do not have color names for waves outside of our tiny visible frequency sliver, even though those other frequencies are no different.
Why the title should always be ground breaking..? 😄😄
It's not ground breaking, it's intentionally misleading.
Because it is. Think about it. Your brain has to make up a bunch of stuff so you can interpret the world well enough to survive.
"Color" is perception. Wavelength (not color!) is the property of the light. Color = mix of wavelenghts plus intensity. Saying "it does not exist" is misleading. That's a cheap trick. I don't like cheap tricks.
"Color (American English), or colour (Commonwealth English), is the characteristic of human visual perception" (Wikipedia). So the characteristic of perception "does not exist"?! Sigh.
@@JustSome16 Yes correct! Colour= mix of wavelengths plus intensity , *But* light and wavelength is a single thing! *And* Colour is the property of light/wavelength
@@deenewyork1962 "Colour is the property of light/wavelength" is demonstrably wrong. Any practical color space has at least three dimensions. Wavelength has one. Clearly not the same thing. Wavelength is universal, color is subjective. Cats don't see the same colors. You see colors when hit by a heavy object. You don't see low intensity light as colors. You don't see high intensity light as colors either. There is more to the color than just wave length.
I love it how you are able to break down these concepts. This channel is a golden nugget on youtube
Man thank you. I never knew how this works. Thanks a bunch.
Thanks for answering my previous questions
We see a leaf green in sunlight because it reflects green light but absorbs all other(like red)
If we keep the same leaf in red or blue light,we should see it black as it must absorb all the red light but instead we see the leaf in red or blue color
Why?
Pls reply
Ever going to look at color the same?
No, probably not. Interesting stuff.
I learned so many things from this channel. Thank you so much.
Probably I know well enough this topic... but explained by Nick is always worthy!
Your channel is growing so fast. Very much deserved!
This guy is so freaking amazing at explaining science stuff. Respect++
respect to you for making sense all that guff
Just because it's all in your head doesn't mean it isn't real. Don't confuse wavelengths of light with color. As you said, there is no color in the physical world. Color is simply how our brains interpret light. By the way, the human red cone has a small spike in sensitivity in the blue range, which allows up to see purple, if not magenta, light.
I was waiting for this comment. Theres a difference between wavelengths of visible light and the pigments used to recreate or trigger them.
Yes that’s really informative,just not crazy as previous ones!
Did you mis the shower scene?
Very nice explanation of colors. Simple and effective.
And for most of us with formal watercolor sets...it really doesn't exist. :-)
Staring at a bright color will temporarily desensitize the cones associated with that color. Stare at a magenta screen for a while and then change it to green. The green light will no longer activate the red and blue cones as much as it normally would, so you will be looking at a super green color that you don’t normally ever see.
This is my new favorite Science Asylum video. Informative, Interesting, Shocking AND Sexy!
Every new Science Asylum video that comes out, becomes my new favorite
"We need a source of light, then we need the thing we're trying to see, and then our eyeballs, and then our brains." You just described what we call the "color triangle" at the color science lab I study at. I was thrilled to see it here! I also love how you touch on the idea that objects are not actually colored. Actually, this video is a really great introduction to color science, in general, with a couple of important exceptions.
First, color is a perception in the brain, not a physical property, which means that your screen DOES show yellow, it just isn't the same combination of light that you would receive from, say, a lemon. This concept is known as "metamerism", if you (or anyone else reading this) are interested in learning more. This is also why any arguments saying "____ is not a color" don't actually make sense. All colors exist only in the mind.
Second, adding primaries is less about increasing the NUMBER of colors available, and more about increasing the RANGE. Despite popular belief, it is not actually possible to recreate all of the visible colors using only three primaries, and the more primaries that you add, the larger the range of colors that you can see is. Personally, I'm all in favor of adding more primaries to screens.
Really loved this video!❤ I've taken to watching videos on your channel to understand more about optics and have found it to be an incredible resource.
"your screen DOES show yellow" ?? NOPE! on most TV screens, yellow does NOT exist!! (search that!) - get a good magnifier, you will see red and green pixels that the brain decodes to yellow..
As before - excellent video. Very well researched and excellent delivery.
Can you explain why the spokes of a wheel, as the car moves forward, move in the direction of the car. But, as the car picks-up speed the spokes give a visual image that they reverse direction? Thank you in advance.
Because you spend too much time on RUclips ?
Sounds like a good video topic.
Actually, I take that back. Add in some contrasts between rolling shutter effects and gate effects, with a spice of interlacing and it could be good.
@@boring7823 Captain Disillusion has been making some quick videos recently on tech stuff like that. ruclips.net/user/CaptainDisillusion
I would really like to thank the person who left a comment on some other science channel recommending your channel a long time ago.
you sir have educated me well on hard topics. For that I can't thank you enough.
I'm glad you enjoy it :-)
If it was on MatrixWisdom BS channel , it may be me...
ok... what i've learned today: even when its dark and there is no light i can see the letters "subscribe" 😎
It's because SUBSCRIBE emits RED light.
That is why in former times blue colour was added to white fabrics to remove a yellow or grey cast. Nowadays optical brighteners are used in laundry detergents, which absorb UV light and emit blue light.
I'm quite disappointed by my brain. But I'm glad at the same time. :D
An actor , a teacher , an idol and a friend who entertains u in his each word
I disagree with the assertion that "colour" = "spectral colour".
You're right, unlike the video. To quote Charles Poynton's Color FAQ: What is colour?
- Colour is the *perceptual* *result* of light in the visible region of the spectrum, having wavelengths in the region of 400 nm to 700 nm, incident upon the retina. [...] spectral power distributions exist in the physical world, but colour exists only in the eye and the brain.
Not me laying awake having an existential crisis over color.
I have a question
Why are you so underrated?
Edit: By "underrated" i mean he has very less subs and views than he deserve.
He is not. Because the ones who know about this channel is in love with Nick and The Science Asylum. So anyone who doesn't know this channel don't say about this channel(for obvious reasons). Therefore, if there would have been people who wouldn't enjoy that much of his content or hate him for his content(but channel quality is same), then this channel would be called underrated, as its content is good and but people who watch the channel doesn't really care about it. But this is not true. Each and everyone who watches this channel loves him and even posts lovely comments for Nick. Hence you didn't pick the right word for your comment....... If you read this comment, then please tell me if anywhere I am wrong.
@@chiefdvm1671I totally agree with you. He makes great content and all his subscribers loves him. By "underrated" I meant he still only have 100k+ subs where other science channels have millions of subs. He makes as good content as any other good science youtuber(or even better) but gets very less attention than he deserve.
Actually very less people care about the wording in this content, so you didn't have to edit your comment😂😂. But I was just informing you that you had done a grammatical error. Otherwise no one cares about this. I have seen many people doing this....even if someone has english as there mother tongue. I don't have it as my mother tongue. No matter. Nice seeing someone accepting their mistake😊
@4:15 ahhahaha I laughed so hard my GF asked to see the video, she NEVER watches my videos
Thanks for appreciating it! (Most comments about it have been viewers disappointed they don't get to learn the bio.)
Bro why you don't have 1M?😢
The more we understand the universe the more we see how the truth is dull and harsh!
Our imaginations are always more magical and beautiful!
This is the video which literally proves :
DON'T TRUST YOUR EYES
BUT! The lights that make up the pixels on your LCD screen have to be chosen to emit particular wavelengths of light! This means that, aside from those three very particular locations on the visible light spectrum, your computer screen is TOTALLY INCAPABLE of displaying the other colors that are actually the only colors that physically exist. The subset of colors that is displayable by your LCD computer screen is called the "color gamut" of the screen. If you were to get a screen that has a fourth color of light built into it, then you WOULD actually be able to see additional colors that the screen could not display beforehand. It isn't a total and complete waste of your money. It's just a marginal gain.
I teach a smattering of this to my Linear Algebra students in high school when we talk about vector spaces. Color gamuts are not vector spaces since it's impossible to generate two colors that will destructively interfere using a computer screen, though. But, there are some really interesting things happening in the science of what colors are perceptible coming from your screen.
“What if I told you the color white doesn’t exist”
IT’S A SHADE.
*video ends*
I thought black was a shade and white was a tint.
This is great! I´ve been trying to do the same thing with wind.
"Don´t think its windy and you are cold. Think there is a pressure difference and your body is losing heat faster"
Its less romantic, but i experience less cold that way

Next video: "the Sun is always painted yellow but it's white instead"

with a thong-sunbathing clone.
Yes. Sun should actually look white :)
The reason it looks yellow is because of Rayleigh scattering. Blue light scatters more and we see the sky as blue.
Red and green are less scattered and reach our eyes when we look at the sun. What is red and green combined? Yellow of course. That's why sun looks yellow.
P.S : the blue color of the sea and oceans is *not* the reflection of sky. It's an opposite effect. Other colors are absorbed more and the blue remains.
I sort of knew this science from school, but I'd never Seen it this way before. Very Enlightening.
The shower clone have marked my mind. O_O
What is seen can't be unseen😂😂😂😂
Dont worry it doesnt exist
Good one Nick. Never thought it would be this interesting.
Next video:
Your imaginary girlfriend does not exist!
ok,ok, maybe my girlfriend could be "imaginary", but would that then mean that my jet black shoulder length hair and my chisell jaw with associated good looks are also "imaginary" , No, i cant believe that . . . looks in mirror . . . OH SH*T !!!!!!
Just do a 90 degree rotation. She's on her own axis. You two added together make a complex relationship!
Like the square root of -100... she’s a 10, but imaginary
@@TheStringfellowHawk sqr of -100 is not 10
Saved this to watch again when I forget. Great explanation. Just enough but not too much
CLEAR is not a color. You should have said translucent!! lol
He said transparent first.
That was heck of a sound argument. Well done, Nick!
I just realized...
School is a lie :|
School must always simplify. If not, at least 50% had not understood what was taught. Even at senior high school in physics class, there are lots of simplifications.
Remember kids still need to attend school , it still is important 😂 sometimes first we need to learn the wrong in order to learn the right
@@deenewyork1962 That must mean that we must learn left before right. 😜
Nice video! I guessed your description but still knew I was going to learn something. Thanks for making it so entertaining!
Thank you for using the proper word for the color magenta! I have been teaching my son the real primary colors and this video is a great overview on how we see colors. Great job 👍
Very random, but could you do a video on how us, as 3 dimensional creatures, can try to envision something of 4 dimensions? Maybe explain that trippy looking cube animation and some of the mathematics involved going into R4. It’d be really interesting to see your take on it!
Nice. I was obsessed with colour perception for a bit, from exploring the nature of brown (which is really orange with a higher blue component) and why it registers more prominently than other 'sub-spectra', to trying to simulate the dichromatic vision some animals have.
this was taught In my school.... and college went even further into it. non the less, it was a fun video!
