“Color is in our heads”. Love how this man just disbanded racism through science.
Totally agree
great point!!
Lol no he didn't. Your statement is quite racist I'm not a color I'm a race. I never in my life seen a while person but have seen some Caucasians
@@MarcusCathey0425 first of all Marcus, the only race you belong to is the human race. And for you to say that statement in a time where no one can be unified on anything is not only selfish but bigoted of you to say. And yes as a black man I can be prejudice, but I can NEVER be racist in this society. So with all do respect, if you cannot appreciate this person trying to do something positive with their influence, than you do not need to be apart of this community. If you aren’t racist than there would be no reason for you to say that when the goal is to love each others as humans. I hope you learn that these statements do not make you a victim.
You had to bring race to a non race chann. F you
I remember being about 14 years old [15 years ago] in science class and asking my science teacher if we perceive colors differently since it's all about perception and they shut me up and told me that this was a stupid question and dismissed it. SO glad to feel validated about that and some of the crazy ideas and theories i made up in my head in highschool
I asked this question two weeks ago and he said yes but the difference is most likely very subtle and hardly noticeable but it may be more for others as in colorblind people

What you have demonstrated is called exposure compensation, it happens both in auto exposure cameras and your own eyes as the pupil open and closes. If you had kept the exposure the same, the room would be very bright, but you would still see the phone as white. Also in the projector scene, i figure there would still be light present due to spill that happens in the projector and its measured by the projector contrast ratio. If this was done on an oled panel, the blacks would be truly black, minus the spill light that would be bouncing around the room and coming back to the dark area. If you where in a void where the light could not travel back to the surface you would see (Or not see lol) truly black (Ignoring the fact that your own face and body would serve as a bounce card). As a photographer i would say Black is the absence of light and any shade above would be gray.
Sounds like the difference between zero and one or any other number.
@@DanJuega Pretty much. Anything above 0 is something lol
@@PopoRamos No, I meant to say that it seems like an unnecessary distinction as zero is still a number.
@@DanJuega Maybe so, what I name the color is just my opinion, based on my observations

@@ste3547 that still is a question the wise man never responded prolly because no one asked
That would be a really cool concept, like anti light!
"Does it matter if its light or paint hitting your eye? It actually doesn't"
Me: splashes a bucket of paint in my eyes
I think the question more revolves around the concept of negative light, like a flashlight that makes everything its "light" touches appear darker.
Almost like an artificial shadow generator, with no light source between the obstruction and the shadow itself.
However, such technology would likely require either physics components we aren't aware of yet, or devices so cold they read in the Negative Kelvin range and possibly cannot exist.
Negative Kelvin range? That's impossible by the very definition of Kelvin.
Only dark matter is known to "obstruct" light. If you could harness dark matter to create a dark flashlight somehow, that would be possible. It is however beyond our technology and is also highly impractical. For what purpose would you require such a device other than as a novelty item?
I take that back, it would be incredibly useful. harnessing dark matter would take camouflage to the next level. It would pioneer revolutionary stealth technology.
Well it is possible. Just imagine you have a flashlight with a parabolic light and at the center of it you just have a solid cover. Now when you shine your flashlight at something, you will have a shadow in the center while everything else around it is lighten up, so anyone looking at it, would perceive the center as dark or black because around it's very bright. So basicly the same phenomenom you can see int he video.
@@maozedong8370sure, it would possible - just need to prove dark matter first, then figure out if it can be harnessed

The fact that I don't understand anything here but surprisingly still knows what's happening
Taking this to a philosophical level, on how the two often represent light and dark, good and evil it just goes to show they're just all opposite ends of the same coin and that perspective is what matters.
From my childhood I always thought about this question that "do we all see the exact same red colour or do we see it just a bit different then the other but since we can't get into somebody else's head so we can not know and there is no word to describe the little differences and we don't realise it.
Edit: i dont know why but if you read replies down there, you will see so many people kinda salty about this question and i have no idea why? It's just a question that i sometimes ponder about. Some tried to answer it and i didn't feel like they understood the question to begin with and then they start acting salty.
If someone didn't accept your answer to their question then just move on na. Why bother so much that it makes you almost sound angry?
Yep

@@Kitulous WE NEED ANSWERS
That’s crazy, I never really thought about how projections show black
they don't
the "black" part of a projection is the absense of illumination
it's not black, it's just a not bright white
and this black casts a shadow because the projector cannot fully block the light that the very powerful lamp inside a projector produces
it's the same with your monitor (unless it's oled, crt or plasma): black color in a TFT monitor produces light because the liquid crystals inside a monitor cannot fully block the light from a LCD backlight
@@Kitulous nice
Projectors show gray not black. Gray is a shade of white but black is not a shade of white because true black is the total absence of light/white.
@@Kitulous True. I was going to say that. The reason it looks like the black has light is because of the bleeding of light from the surrounding area.
@@motelghost477 that's an useless way to define black
So the bug crawling around on his background screen is really a white bug that’s looks black because it’s absorbing more light than all the surroundings.
I noticed that! It made it easy to catch the edits, as the bug blinked in and out of existence. 😄
The thumbnail promised me the flashdark, but the video just delivered low levels of light.

This is a nifty video, it actually made me think of a previous video I saw about how three dimensional objects would not be able to see four dimensional objects. Its neat how he describes the differences between paints and light rays, also makes sense considering how am prism breaks light into other colors but not black or dark colors.
Makes you thankful for having the kind of eyes and brain we have in our heads.
Also might be a key to finding ways to see in different wavelengths of light, if it comes from our mind.
I might be sounding a bit weird, but it makes me think of what else our eyes may be missing in the emptiness of space.

Improvement?
Short answer: no
Long answer: HELL no
Long answer. Black is not a color, and although it is percieved by our eyes as something visible, it is actually the absence of light, therefore it is utterly impossible. It is all an illusion depending on how we perceive it through our own eyes.
You’re describing subtractive colour mixing and it’s the first time in my life the “colou” black has ever made sense to me.

Holly crap. This is crazy! But frigging awesome
Yes! Color is different between each person. Blood sugar levels have a lot to do with the difference of color intensity that each individual perceives! I remember a while back working at a photo color print facility after lunch or break people would "over filter" and decrease contrast of prints because their blood sugar was high after lunch and they perceived color too strong...the prints came out kind of "flat"! Just the opposite happened when people were fasting or hadn't eaten for a long period...they perceived less intense color so they intensified the colors so the technician would feel they were normal, but they were very contrasty and color intense! We ended up monitoring when employees ate and had healthy snacks out and available for them to eat! Most however, preferred the little squares of snickers bars! Same goes for photoshop, and digital printing facilities!
Whoa!
Wow that's crazy
That makes so much sense! I believe it's to help encourage people to eat sugary fruits. I've noticed when my blood sugar is low, fruits look really vibrant and I feel like shoveling them in my mouth, but when my sugar's really high, the opposite seems to happen.
Is that why when I drink 6 energy drinks in a row I see colors better
Seeing the same color for a prolonged time has a similar effect and you can try it yourself!
Quickest way to do it is to close your eyes and cover one of them with your hand.
Then look into a relatively bright light so one of your eyes starts seeing red while the other sees black.
Wait for a couple seconds and turn of the light and look at a normal room with one eye at the time switch between them and you will see the one you had covered sees the reds a lot stronger then your other eye who will see everything in a more greenish tint and all the reds will be relatively weak.
So you're saying that MY pink, could be somebody else's BLUE?!
@Yensen Connor You're confused. Hehe
Thats whats been in my mind long ago.. it still haunts me
Your profile picture has so much blue color on it
No
IAMDAONE same
Enlightening, no pun intended. Temperature is similar. For instance an air conditioner does not put cold into a room. It removes heat from a room resulting in cold air. So hot and cold are basically the same too. Cold is just a lot less heat.
I was expecting this to be something cheap like UV light, but no, no, you did deliver.
Being color blind, I can definitely say we see colors differently. What most people don't understand is that most colorblind people can still see all the colors it's just some are really hard to tell apart.
I have that problem, but I passed the color blind test. I still think I have at least a color blindspot.
I've read color blind people can actually see camouflaged people easier.
True, in my case its just some shades of green and red
@@UHFStation1 that's true. I always wondered how people fall for camo until I read that. I cannot do those hidden picture things though and that might be the colorblindness as well
@@UHFStation1 That kind of makes sense, since the camo would be designed for people with normal trichromatic vision.
I got distracted half way... That Bug though!!! Was it Black?! Or was it White?! Or was it a shade of White that looks black!!!!
Yasinx63 or was it blue, green and red? Absorbing more light than the background
I like how this was something we subconsciously knew but not consciously because of the fact we experience this all the time 💀 (i.e. going outside while the sun is out and the phone being all dark)
Great point, “how can we be sure we are seeing same color”, what I see yellow could be perceived by someone else as different shade of yellow or even a different color.
The concept that colors for one person might not look the same to another person is something one of my friends and I thought up during free time in grade school one day "several" years ago. I didn't know there was actually people researching the concept. That's neat.
Wow, same, actually. Idk why I never searched it up, but I thought it wouldn't be there and that I was just crazy. Maybe our favorite colors all appear the same, but... aren't? Idk how to say this...
@@PxndaCakes Yeah it’s interesting. Yes, our brains perceive light based on frequency and there is a substantial theory behind colour which explains colour interaction, but what our brains perceive as brown or red or blue seems like it could be completely arbitrary.
This specifically is not really being researched all that much these days but that's simply because the idea goes back to Aristotle, Plato, Democritus, and Empedocles. Way back then, there was debate among philosophers about whether color originated in the mind and was projected onto an object or originated in an object then was interpreted by the mind.
That said, how people perceive, interpret, and communicate about colors is still being studied in linguistics and cognitive psychology. Neuro psychology also has some fun research on making impossible colors that cannot exist in nature but you can trick the brain into thinking it sees. To learn more about that research, look up "stygian blue" and "hyper green".
yes! like what if my red looks like your green but we both call it red because that’s what we’ve been told is red
Well, I'm glad I'm not crazy alone lol
I've thought about it many years ago also, but never really looked into it, but always love to question people about it
As far as the "We can never know if we see the same color as everyone else," you can, at the very least, know that it's hue shifted and not random. Or rather: all people with good vision and without color-blindness can fairly accurately "order" colors/ hues in sequence. So even if one person's red is another person's blue, ALL of the colors are equally shifted to match the same hue transitions (like adjusting a hue slider across an entire photo).
That's partially true. Remember, the human eye uses 3 "big blocks" of color for the entire range of visible light. This means color cones (photoreceptors) can be swapped. This also means that if someone has red and green swapped (blue intact), yellow will still look the same and will still be located at the same wavelength in the spectrum. If all cones were shuffled, some secondary colors would swap with other secondaries. This color swapping can only be done physically, because it requires "incorrect" neural connections of cones. The hue shift you were mentioning, can only be achieved purely in the brain because the brain is the one processing the color spectrum and making assumptions (bias)
@@Rudxain Indeed! Hence my mentioning of "good"/ healthy vision :)
@@Rudxain I'm not sure about that because we're being taught rules to name the colors, so unless the swapping occurs after the learning process, or perhaps a "return to normal" occurs, we'd be taught that red is blue and so on, and only by reconciliation with the spectrum would we know any difference. We assume color looks the same for each of us, but that doesn't account for why we find some colors more attractive than others, favorite color for example, and some people don't have a favorite. Or why I can't see gold in the dress on the screen. I thought it might be a screen adjustment, but my wife can see it. I might be color blind and don't know it.
What's even more intriguing is that we're now engaging in debates over whether light is a particle or wave, and it could be both. Or we could be just plain wrong. They're also adding field to the debate.
@@minerblake7494 Exactly, I agree. And you can check if you're colorblind by looking at 3 RGB bars:
1. Open some paint program and create a rectangle set to #FF0000, then another as #00FF00, then #0000FF.
2. Now you should have 3 rectangles with max saturation. Green should be the brightest, followed by Red, then Blue. This happens because blue cone sensitivity is lower than the other cones. If you see a very bright blue, then your display is bad *OR you're tetrachromat.*
3. If you aren't convinced, test the same image on multiple displays of different technologies (LCD, LED, OLED, QLED, Plasma, and CRT), with all "special settings" disabled (image "correction" reduces fidelity by applying a bias). And also use secondary colors (yellow, cyan, and magenta)
@@Rudxain Pretty smart, I'll try it thanks.
You have brought up a very interesting point, I believe we do see colors differently individually, not all of us but possibly a good portion of us see colors as slightly or more different hues. I say this because I am a musician and a great example of frequency interpretation by an individual is the audition section of American Idol, light as well as sound are frequencies that are interpreted by our brains and it is pretty obvious during the auditions of American Idol that some do not interpret sound frequencies the same as others hence, it must be the same for light interpretation.
Thank you extremely much for your video. I just have a few enquiries.
Can color be contributed to the fundamental decomposition of the medium through which is being observed and is the intensity of the specific shade of light correlated to the magnitude and frequency of the different types of molecules and atoms, meaning can the type of shade be contributed to a particular object with a abondance of a certain molecule or atom making its absorption and reflection of photons consequential to the color of light observed?. And if so then can the light of a set object be change inheritably by changing the medium through which its being observed? For example will the color of a green shirt change in a air rich environment to another color if its view through just hydrogen in a vacuum chamber?
As a child and up until now ive always questioned whether we really see the same ‘color’.. thank u for explaining that really well. Im just a lazy person who loves to be spoon fed of sciency stuff

That was such an excellent explanation. Thank you for the brain food
In your projector experiment: In seeing your shadow in the black circle of the projection, I think that experiment is simply experiencing a) the inefficiency of the projector, and b) perhaps some diffusion of light through the atmosphere. FYI, this is related to why OLED TVs do better with black then LED LCD counterparts. OLED emits zero (or near zero light) while the LED LCD can't make a pure black because of washout of the technology. Black is the absence of light. The "black" you see on the projector is just shades of grey that want to be black but can't with that technology. :)
I do appreciate your point on the fact we can't be certain if we all interpret the wavelengths of visible light the same internally in our brains. Fascinating.

He doesn't sub-bot. That's why. Nobody actually gets these large amounts of subscribers superfast without sub bots.
Avaneesh Srivastava it's bcs his voice is annoying no offense
He is almost to 1 million!
most people just want to watch the kardashians. that is the reality of the world
Maybe to you. I thought it was a little strange at first, but really it's just unique and I don't get out much. XD
Also, adding no offense doesn't make it any less offensive.
This is one of the best teaching i've ever watched, and it mind blowing
Quite interesting, Action Lab! The lighter and more bright an object is to another, the darker and less bright it'll make the other look to an observer. Shadows could look dark when there's brighter light surrounding them, but they also still hold a very dim source of light in them. When there's absolutely no light or energy in something, it would look pitch black in all cases. Maybe like black holes, for instance.
"Colors are in our heads."
Totally! The colors we see are there in relation to each other, but they aren't really how we perceive them as. Other animals could perceive them differently, and that makes us wonder, "Are we living in reality or just in our perception, nature made it, for survival purposes?"
Keep up these videos, man! I love them.
6:08 is a question I have had since I was around 8 years old. Definitely still fascinating to think about 22 years later.
"How do I know that my understanding of the color 'Red' (for example) is the same as Jimmy's understanding of the color Red? What if his 'Red' is my 'Blue'? Or something else entirely which I could never even imagine?"
Butr there is no 'red' in your head anyway because colours are simply fictions the brain lies to us about although there is a difference in wavelengths of light which our retinas message the brain about & then the brain makes up a fiction based on that data. If I were ask you to forget about wavelength difference between yellow & blue & state how they are any different all we can say is that red looks red & yellow looks yellow to us but there is no experience of either as such, only an illusion of each one. This is why some people think they see a yellow & black dress & others think they see a black & blue dress since there really isn't any colour there at all only wavelengths interpreted as total fictions. If they weren't fictions we would be able to say what makes the experience of yellow different to the experienc of blue but we can't so we say yellow looks yellow & blue looks blue because we can't think of anything meaningful to say about the mature of each experience. That wouldn't be the case if the experience of colours was real rather than fiction.
That is true we could have same names for different colors according to different people but they would have to be the same intensity which makes it very hard

I'm not the only one?
Vsauce's video. Check it out.
The phone in front of the brighter screen isn't producing blacklight, its just the exposure of the camera (or a human eye) adjusting itself to the brighter light.
If you are outside on a sunny day and look across the street into your neighbors house windows you can't see inside because there is less light and your eyes can't focus on the rooms inside, but your neighbors can see just fine in their house. And at night, you can see into your neighbors lit house but they can't see you out in the dark because their eyes are exposed to the brighter light. Yet, if they walk out onto their porch they would see you just fine.
This comment needs more likes.
It's how camera aperture works.
So If I would murder somebody I should do it in nightime so that they wouldn't see me outside ready to kill them.
Thanks great tip.
Mark G stop sneaking or stalmi g your neighbor s
Mango Rage not fully exactly,you would need to wear all black to actually not stand out less, black clothes tend to absorb everything around them, so if you were to wear white clothes that reflect everything to give off the color white they would reflect from other colors such as roygbiv (red, orange, yellow, green, blue, indigo, violet) this will make you stand out much more as other colors around you would want to reflect with your white clothes, therefore wearing black would be the best choice because it'll want to absorb the colors around you, if you were to wear any other colors like orange it'll try to reflect to orange rays so it can turn out to be orange just like red it'll want to reflect to red rays so it'll look out red, you see if I were you I would wear black
best science guy with really high knowledge
What you explained in this video are amazing, thank you ❤☀️💚
I'm just watching the bug in the background😂😂😂

Where?
Me: *Only here to see dark light*
The action lab: "Oh heres a dictionary about colores and light"
lol
Correct me if I'm wrong, so white and black are basically error codes in our minds for the colors we can't see? I thought this because butterflies can apparently see like 12 colors in their spectrum vs our 3. So do our 3 colors make another color for butterfly's we cannot perceive? Im pretty sure it would.
It is frightening how correct the principles of the Kybalion are regarding nature. Truly amazing.
The ultimate black is the total absence of light. Your projector does not project black light but a small amount of light, filtered by the LCD panels. And those LCD panels can't filter the light totally. This is why you still can see some light on the darker area. This is also why DLP exists.
Thank you !
And also why it isn't "black light", but just a shade of gray. People sometimes forget how to brain.
Francois Scala I scrolled down to the comments to see the LCD/ DLP note.. Thank you ...
I'd mention also that the first trick about the light panel & the phone ,, the phone turn to black as result of lack in dynamic range of the camera in this extreme scenario. Or/and because the 'auto' exposure option in the camera which adjust according to the brightest object.
ultimate black is the total absence of light, while the percieved "black" is the relative absence of light to the surroundings
Alex939 there is no "grey light" either, it's just a dimmer white
Man, I’m staring to think you’re secretly Vsauce’s long lost brother. You really make me question reality sometimes.
ya
Yup
I have something in my head, like your projecter experiment what if we watch the screen from a mirror placed at side of projector and try to watch that black ⚫ , it will look black (I think) but it will look black also when looking from mirror to screen so what about while light?
Ohhh so that's why I got 4 shadows with different type of black when i get out to the sun 🤔interesting...
This man just solved racism.
lol this comment is woke af..
lmao
Lol
Black is just a different shade of white confirmed
Prove of all men created equal? :P
His explanation about paints vs light answered a question plaguing me my entire life lol. I love this video!
I always thought about this and even discussed it with my brother that's great you made a vid about it
Aight lets be honest every video that was made four years ago is the best thing ever
3:50 man, there is a spider behind you above your head

Lol
It's good luck

On that note: he said color is just something in our head, that's wrong. Imagine that's right, then sweet and bitter is also something in our head? NO. Even though the sensation of colors, or tastes may be different among different people, but they have confirmed among billions of people that the same thing tastes bitter, it also tastes bitter to other people, as to what bitterness really feels like to any individual person is largely irrelevant. To go even further, how it feels tasting something bitter is probably the same among people. I know that because people use language to describe it, that's very much the same.
@@seanleith5312 I came here to laugh at the original comment, but what you said is just so true!👏👏
@@seanleith5312 how can u be so sure? It's still in our heads anyway :(
@@seanleith5312 Colour is the emission of a photon when an electron gets knocked up to a higher orbital and then falls back down. Our eyes are sensitive to photons but our brain 100% translates that into an image that we see in our heads. It’s been proven that people perceive colours and shades differently from each other, and that’s because of the differences in how our brains perceive the light. We aren’t seeing actual light when we see what’s around us, we are seeing what our brain interprets from photons coming in to our eyes based on wavelengths. The end result is the same, but colour isn’t inherent in our universe, it’s only what our brain interprets it to be.
@@seanleith5312 That's still all in our heads, it just so happens that we are all human and therefore have fairly similar brains, thus we tend to find the same things bitter.
You have no evidence that we taste things the same way. Using similar words is just evidence that our language teaches us how to describe our experiences in the exact same way.
He explains the concept so well.😃
Not quite the same thing, but this reminds me of that optical illusion where two rectangles painted in the exact same shade of gray seem like they are different, based on the white or black margins placed around each.
