dude everyone is watching this for school I'm just here because this is actually interesting!
Nerd
Code _Encrypt jeez bro. Idk where ur from but where I’m from calling someone a nerd is barely an insult. It’s more of a joke.
Code _Encrypt not where I’m from. But I’m not saying ur wrong. Mabye that’s just how it is where you live
I agree with you
Me too
Hats off to the presentation. Every word in the explanation is supported by animated graphics. complex Concepts are made very simple. Thank you . I learnt lot.
I'm just here because my teacher made me watch this thing
Same dude 😂
amen
Same
Same
Same🤚🏻
You could elaborate more on the way the signal of colour is created, but it's something I already know... Great video, quite informative!
Beautifully explained ! I hope i saw all the colors in it :P
We really don't know if any of us sees the colors the same way, not even the light itself. If it, by theory, hits the rods and cones and is being transformed into electrochemical impulses, we really haven't got even the slightest idea of what it really is, what the nature of it is. We only see the holographic image of it in the darkness of our skulls, the image our brain interpreted/created, but we don't know if it's really like that "out there".
That’s a valid scientific argument. The idea you are talking about has already been presented in a theory which is called “model-dependent realism” in cosmology.
This video is so fascinating. I'm watching it for Photography class, but I find the information so fascinating. I just wish I could focus, but the weird music/noise in the background is making it impossible. Everything else about this video is perfect. Just the background noise...
I’m here because i have some homework due tomorrow and I’m doing everything last minute 😬
Highly relatable as I’m planning a chem lab on the toilet...
Art hw for me as well
Tina David me too.... I think Physics is boring though...
so me
Tina David same
I was so confused about colour before, but the was so helpful. Thank you
How does our mind interpret this data such that we 'see' color?
Yes the mantis shrimp picasso could paint hypothetically could paint in more colors of the spectrum but we couldn't see it. Lol
The thing with the mantis shrimp, though, is that we don't understand how it uses those receptors, so it might actually be the opposite. That is, it might only be able to see twelve colors total.
My mind just got fucking blown. Ever since I was a child, I've asked myself "I wonder if there a color out there that we've yet to discover or are not able to see."
This is fascinating indeed. It'd be great if humans involved in the very far future and developed an ability to see at least one more kind of "color".
+Fantasy☯Fangs Scientists have discovered a woman with an extra type of cone, meaning she can see colours described as "inbetween red and green". With all the colour combinations she could possibly see around 100 million different colours, instead of just 10 million. Some scientists believe that up to 3% of the female population could develop this trait.
We do not "see" color. We experience color. Color is an evolved experience. There is no information about color in energy. Energy is merely correlated to the experience of color.
Thanks this helped me for school
i have a question, at 0:17 she said world of predators? what did she say at that moment?
My science teacher used this video for us to use our homework.
Kelly Figueroa art hw for me lol
@@skizama Kelly Figueroa art hw for me lol
Great video!
So does this mean that there are more colors than we know of? 3 vs 12 cones--or am I over thinking it?
Irving Lopez Yes...that is correct.
Irving Lopez Yes, but they are not really "colors" as we have defined them. "Seeing" is simply using organs (i.e. our eyes) to detect a portion of the spectrum. We can't even imagine what these non-visible portions of the spectrum might "look like", because anything we come up with would be restricted only to what we have experienced firsthand--colors. It's like trying to imagine a 4th spacial dimension. It's amazing to think about how much of reality we are "missing" out on!
Yes,there are colours we can’t see that other animals can.
so....what is the actual color of things???? If robots ever become self-aware, they wouldn't have human eyes what would they see?
larshoneytoast33 someone told me that ghosts have color but we cant see it. out of visible spectrum
They wouldn't be able to see at all.
bradley Spiteri .The Colors you see are no different than the real colours.
We perceive an apple as red because it consists of color pigments that absorb the blue and green wavelengths of light and thus only reflects the wavelenghts that we, as humans, are able to interpret as a red color.
Let's look at it this way. A lemon absorbs the blue light and reflects the red and green portion into our eye thus making in it seem like it is yellow. If you shine light with only the red and blue light spectrum onto a lemon it will appear red, and black if you only hit it with blue light.
As to your second question. Your hypothetical robot could be equipped with the tech straight out of a digital camera and interpret the reflected light intensity and wavelenght the same way by storing the information as numbers.
They wouldn't be able to see. They would have a programmed "navigation" or just a sense for navigation (= their vision system). It's hard to explain. But I don't think it's possible to "create" a vision... It can't be made.
cool video
very helpful for my project :3
thanks, but how do we percieve the indivisual RGB pixels on a TV? i close up to the tv, a yellow color from afar, is red and green up close?, how do i see it as yellow??
the green and red is combined
This is genuenlly interesting
Maybe I'm the only one here that isn't sent by a teacher.
I just want to learn everything.
good on yo, mate
I'm here because my son never stops asking for videos on scientific topics
@@DrMitharos this made my day haha
My mum forces me to do homework so I watch videos so that I can have fun at the same time🥴🥴
We are able to see colours because when light reflects off an object into our eyes it first hits the cornea a film that lays on top of our eyes, this layer refracts light towards our pupil which gets bigger or smaller to let in more or less light. Once light passes through the pupil it is sent to the lens which angles and focuses the light to a point on the outer layer of the retina, here light-sensitive cells called rods and cones send information to ganglion nerve cells in the inner retina. Ganglion cells then send the information to the optic nerve, which sends the signal to the brain, where the signal is processed and interpreted. Rods and cones, the two types of light-sensitive cells located on the outer retina, have different jobs. Rods are responsible for our perception of light and dark and our peripheral vision. Cones are what allow us to see colour. They are found in the centre of the retina, where light is focusing. Cones come in three varieties, each sensitive to a different light. Interestingly, we have more cones sensitive to red light, meaning our vision is best for warmer colours like reds, oranges and yellows. However, our cones aren’t sensitive to light with wavelengths shorter than 400 nanometers or longer than around 700 nanometers. For example, a gamma wave’s wavelength is about the size of an atomic nucleus, which is much too short than any of our three types of cones to sense. Radio waves are too long, with wavelengths longer than two empire state buildings put together. That doesn’t mean that these forms of light aren’t visible per se. Other animals have different kinds and number of cones, which allow them to see the world differently than we do. Dogs, for example, are more limited in the wavelengths they can see because they only have two types of cones leaving them “colourblind” to differences between red and green. Butterflies have four types of cones in their eyes, letting them see ultraviolet light. The animal with the best colour vision might be the mantis shrimp, which has 12 different kinds of cones. If Pablo Picasso and Paul Klee created amazing works of art with just three types of cones, imagine what the masterpiece the mantis shrimp would create with 12!
Didn’t she say most of this
I wish the song was an actual song and not a remix lol
I'm just here cuz my teacher made us watch this.
The Voltic Shock lol I have to do a project bout it ugh!
me 2
Same
So if we think an apple is red but to a mantis shrimp it might not be. So what is the true color of red? Is there a color at all?
It's because color is an illusion. It is not a property of matter and it isn't a part of the real world

Who else is here after reading/watching/listening to The Colour out of Space?!
Colored light?
Espectro de luz electromagnético contiene el espectro de luz visible.
Existen células receptoras que nos permiten percibir la luz del entornos llamadas Varillas y Conos.
Varillas (Rods): Responsables de nuestra percepción de la luz y la oscuridad.
Conos (Cones): Nos permiten ver el color. Se encuentran en el centro de la rutina. Vienen en 3 variedades (azul, verde, roja), seres tricromáticos. Tenemos más conos sensibles a la luz roja, lo que significa que nuestra visión es mejor para temperaturas más cálidas (rojos, naranjas, amarillos). Rango de ondas percibidas por el humano( (400 nanómetros a 700 nanómetros).
Los perros y gatos tienen 2 conos: Sólo perciben entre el azul, amarillo y el verde. Dejándolos "daltónicos" a las diferencias entre rojo y verde.
Las mariposas tienen 4 conos: Pueden percibir la luz ultravioleta.
Los camarones mantis tienen 12 conos, son sensibles a un amplio rango de intensidades de luz, permitiéndoles ello percibir simultáneamente elementos muy oscuros y muy brillantes dentro del mismo campo de visión.
colorblind people: get a load of this guy!
POV:your teacher made you watch this.
When she said cornea her accent was thick
She speaks like a black person (English-speaking Caribbean) from Canada.
French-Canadian blacks sound different.
Even if a mantis shrimp would create a masterpiece using his 12 senses of colours
We would only see colours which we can interpret and so it won't be a masterpiece
Schooool
colour doesn't exist outside of thebrain, all wavelengths are the same colour in the the world, when the different wavelengths reach the eye the energy levels of those wavelengths get detected and then sent to the brain, the brain is what creates the colour, each wavelength gets ASSIGNED a colour - the universe has no intrinsic colour.
I am not doing this worksheet.
so my theory is true i spend a month on discovering this on my self
got it exactly right but when i told it to people they said i had mental disabilities
Hola a los del 2A del itea
Who’s watching this for school
wow i'm dumb
hi
i thought it was 16
8y1 science bois assemble
I’m here because my teacher said I had to watch this
Say what are they talking about.I'm glad l am stupid.
Disgusting.
Yeet
whats that
I HANK YOU FOR THE PART THAT SCITOONS PLAYED IN MY LIFE. HA. HELLO EVERYBODY. EVERYBODY HELLO. HOW ARE YOU U U U TELL ME HOW DO YOU DO O O O. LONG TIME MI KNOW SEE ANYBODY HOPE EVERYBODY MELLOW. WHAT IS NEW EW EW EW. TELL ME HOW DO YOU DO O O O
you good?
I think this dude just had a stroke midway through a conversation
I hate that smug mantis shrimp so much. Look at him, winking his eyebrows at me and being all cool thinking he's better. YOU THINK YOU'RE BETTER THAN ME MANTIS SHRIMP? HUH? THINK YOU'RE SO TOUGH?
spelt colour wrong
No, ..u did/do.
lol, Dont you know Western (American) English? ...
@@michaelbb1441
Both spelling colour and color are correct :)
@Tony" Yes, i know this, lol hence why i said what i said
"R8" said the uploader spelt Colour wrong. (as "color"), and i said.. yes, ..in Western/American English thats how we spell "color"....
one and a half minutes and that "music" (noise) has me outta here
I guess everyone believes this
I’m here because of school and this boring
Cleshette Nash no it is not
My teacher gave me this for homework BORING!!!!!
lame
