Can Light be Black? Mind-Blowing Dark Light Experiments!

In this video I test if light can be black. I show you several experiments that show you cases of light that is black and then I talk about what color actually is and why mixing pain and light give you the same but different results!

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.

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!

Is that why when I drink 6 energy drinks in a row I see colors better

[@noahwattel4226]

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.

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.

[@friedrichrubinstein]

Negative Kelvin range? That's impossible by the very definition of Kelvin.

[@maozedong8370]

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.

[@sugarraybow]

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.

Or something else entirely which I could never even imagine?"

[@paulbrocklehurst3639]

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.

It,s actually true. Different animals see same colors different.because of structure of how much light can get through it,s cornea.

[@DapperDanLovesYou]

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).

[@Rudxain]

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)

[@DapperDanLovesYou]

​@@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.

[@Rudxain]

@@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)

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".

“White” light is all frequencies of light. “Black” is the absence of light. The “black” light happened because you over powered it with the surrounding light. The outer white light (in a sense) took center of attention, causing the inner light to be black.

[@dasun13]

Yeah. I assume that it's when you try and look at your cell phone screen on a very bright day outside. It becomes virtually black. White black

[@generalwolf35gaming]

Ya. Another example is looking into a window of a house in a sunny day from a little ways off. It is really hard to see inside. There is light exiting the window (from inside) and hitting your eye, but the light bouncing off the house’s outer wall are taking up all that you see.

Yeah, Shadow is a true black, and Vantablack is the blackest black. Any shade of color can fade to black, it's a function of luminessense, and occlusion, or absorption of light. Black when back-lit is a thing, and is NOT strictly a function of surrounding light circumstance, it is also a function of eye sensitivity and wavelength. To see what I mean, use any back-lit LCD or LED display. We've all seen the TV, Monitor, or Cell phone displaying black but "know" its on, and if its dark enough you can slightly illuminate a room with their light in pitch black depending on the quality of their contrast's "blackness" function.

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.

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

@@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.

[@some-one-else]

@@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.

[@teachoc9482]

Wowwee wow wow! That is soooo cool! I luv how simple your experiments are, so I don’t have to strain my brain to understand!

[@AHelpingHand]

I'm sorry, but this is incorrect. Color does not just happen in your mind; your interpretation of color happens in your mind. The physical reality of color is in the wavelength of light. To understand color, you need to understand the physics of light and why different wavelengths register in our eyes as different colors. To say that black is a color of light is to say that silence is a form of sound. First of all, brown is not just a darker shade of orange. It's what we call a "broken hue." It's what happens when you mix complementary colors in such a way that your eye cannot interpret it as one or the other. The wavelengths effectively cancel each other out and neither color reflects properly, but your eye is still stimulated by the presence of light. Subtractively speaking, there is only one way to get purple. There is only one way to get orange. But there are many ways to get brown. Second, there is no flashlight you can make where you can shine it onto a white wall on its own and generate a black spot. It will only look that way comparative to brighter white light around it, and it's due to the absence of white light in that spot which is due to the shadow cast by the object casting the dimmer light. All you are seeing is a comparative dimness, which is why the cell phone trick he shows doesn't work without that back light behind him. Your pupil is contracting to guard against the bright light by letting less light in, and because of that, the amount of light coming off of your phone screen no longer registers as white. Also, if your phone has an adaptive brightness setting, it's going to adjust how bright the screen is based on how bright your environment is. The brighter the environment, the dimmer the screen; the dimmer the environment, the brighter the screen. If black light existed, then there would be a degree of focus and intensity that would allow you to make a black laser, but you can't. Nor can you make a brown laser, because light that has not yet been affected by a variety of different atoms will not produce a mix of photons with different wavelengths. Which is the same reason a prism will not cast brown light in its spectrum, because each wavelength of light passes through that medium at a different angle, but the overall speed of light is unchanged and each wavelength's frequency remains consistent as they all hit the surface at the same time. The white light that is reflecting from a black object is not due to its color, but due to its texture and fresnel. Color is determined by a light wave reflecting from an atom during a drop in its electron orbit that matches the energy difference of that drop. The amount of light reflected back from any given surface has to do with diffusion across the texture of that surface. The rougher it is, the more the light will be diffused because the light hitting it is bouncing around in the tiny valleys of its irregular surface, casting tiny shadows, and sending the reflected light off in different directions. It's why a wet street is shiny, because the presence of that water fills in the pores and smooths out the average surface height, which sends more of the reflected light off in the same direction. Which is the same reason a black ball polished to a mirror shine is going to appear completely black in some spots, completely white from the exact point of light contact, and very close to the color of whatever surface is behind it opposite the point of light contact due to the light being reflected from that surface.

A Helping Hand color is actually processed through your head. Ever heard of how colorblind people see their own color?

[@joshuavaughn2713]

Literally one of the first rules of light is that all color is reflected light, and white light is all color and brings out colors for our eyes to perceive. Conversely, black is the void of light. That “black” in the projection was essentially just a very very very dark gray. It was a product of white light, so it could not have been truly black. The theory about perception of different colors, well, he hit around the meat of it. We all perceive the same colors on their respective wavelengths, but nobody can definitively say we all see them the same way. We are still seeing the same stuff. It’s just that when I look through someone else’s eyes, grass could look purple and the sky could be red. But to that person, it’s just green and blue respectively. That’s how they’ve known those colors. That’s why so many color blind people don’t even know it, because the diluted grayish values that result from the colors they can’t register due to a faulty or absent cone in their eyes is just that color to them. Like in the giver, when the protagonist starts to see and apple be red, as the color blindness wears off, he has no clue what’s going on because the apple was just always gray. In short, this video would have done well with more research and it was well deserved of my dislike.

Here's another fun one to show how our brains "create" color. The visible light spectrum runs approximately 400 to around 700 nanometers in wave length (the actual wave lengths vary slightly, but this good enough for demonstration). 400 nm is violet/blue, while 700 nm is at the other end and is red. Now, here's where it gets interesting... on the scale of wave length, green is near the middle of red and blue, it's around 550 nm wave length. The secondary colors are between these three, yellow is between green and red at around 600 nm, while cyan is between green and violet/blue. If we consider wave length, literally every color has a wave length....with one exception. Magenta. Magenta is a totally made up color by our brain. There is no wave length for magenta. It's a purplish color so would have to be a mixture of reds and and blues, yet green is in the middle. Magenta is simply not there. It's an extra-spectral color made up by our brains.

Have you ever wondered how they can project black in the movies? Me: no

[@michaeldominguez9619]

Yoda Master lol I'm thinking how do you reflect black light?

[@tadeuantoniopassarelli1327]

Black is absence of light,

[@Dunkelelf3]

no not really.. because our brain is strange sometimes.. you know those black spots on the sun? it's the same fuckery as with the backlight and the phone in the beginning... those spots are still very very very bright but a little less bright than the rest of the suns surface around them.. that's why they APPEAR black to us compared to the rest of the sun while in reality still emitting so much light that they would blind you very quick..

[@w.t.h.2040]

tadeu, antonio Passarelli Yes absence of light or absence of light in relation to a more bright light ^^ But funny thing is that the black light is the light that is everywhere basicly. And the white light only from a source.

I'm loving your videos dude.

I can make an apple weightless. I put an apple in your hand, and you'll feel the weight. However, if I put a 30 kg weight in your hand and then add an apple, you won't feel its weight adding to the total. Ta-da! Weightless apple! This is the same principle as the one you're using to prove that the phone emits "black light". Small increases of a metric are noticeable in small numbers (adding 1 to 10 is perceptibly noticeable), and less noticeable as the number increases (adding 1 to 100 000 is not perceptively noticeable). A dim light in total darkness: noticeable difference from pitch black. A dim light in full daylight: not noticeably brighter than full daylight. With a camera it's not much different. Cameras have a limited dynamic range, as do monitors. And so anything outside that range will appear either totally black, or totally white.

[@BlaineShillington]

Great analogy. This guy should be in marketing. haha

[@albeyjames8521]

that is cool dude most likely completely true

[@_Stin_]

The correct explanation. Bravo! It's all about the gamut. No need for linguistic trickery ;)

[@azurethi2851]

I agree, from a purely physical perspective in terms of photons (or apples)... but his point was more on perception. To think about it further, the human eye only really measures RGB and estimates the incident wavelength by how close (relatively intensity) it was to each point. So you couldn't ever see the difference "true" yellow light at 570(ish)nm and the combination of only RGB (no 570 light present) hence computer monitors working. If you really want to marvel at weird perception related things, I'd start with the V-sauce video "Is Your Red The Same as My Red?".

[@shadebug]

He needs to do the phone on the bright light thing again but turn off auto-exposure on his camera

[@v300]

You are confusing the terms. The Absolute Black, or just black, is not light. It is the absence of light. Everything else, even 0.000000001% super dark gray is a shade of white, and it is light.

[@darkchoclate]

He is not saying about black. He is saying about how black light is generated.

[@nathantaylor4101]

Thank you from a camera man

[@pawnmusic]

Its cool...its this new version of millennial science where you can just say whatever the fuck you want because people are stupid and will believe anything....especially if its on youtube. He also said that color discrepancies between people are due to “preconceived notions”..which is utterly false. It depends on the number of cones in your retina..

[@nbtstan3198]

And now imagine how many teachers are confusing terms when teaching kids irl...

[@SheyD78]

Actually its all a matter of perspective and preconceived notions, since colour can be perceived differently by different individuals, which means the colour one person sees when looking at something red is not necessarily the same colour that another person sees, even though having been raised and taught that this specific colour is red both would call it such. The actual colour we perceive differs based on our eyesight (ie cones in the retina as you said), but our education would attribute "red" characteristics to that colour, even if you're actually seeing it as say blue or green. Different again would be someone who is red/blue or red/green colour blind since both look the same to their eyes.

[@highlifemusic8916]

I’ve always asked myself as a kid, and still comes to my mind randomly to this day, ‘ How do we know we all see the same color?’ I love that you brought up the same question. My best theory within my own non-scientific brain, is that, we probably do all see the same color. Generally speaking, certain colors make us feel a certain way. In a room full of yellow, many people feel anxiety. In a room full of blue, people seem to be more relaxed. The correlation between emotion and the visual of color, is enough to convince me that we must generally see the same color, even if perceived differently. But very interesting to see you shed ‘light’ on this subject. Lol

[@nickeni3050]

I've also had this question for a long time.. like what if the sky I see is actually the colour green and the sky someone else sees is red but because we're taught from a young age that the sky is blue we proceed to believe that particular colour is blue whenever we see it despite the chance that we may all actually be seeing a different colour but calling it the same name But we'll never know since we'll never be able to see through another person's eyes

[@super2068]

We have the same equipment to process visual signals. So I would say we see the same colors. If this doesn't convince you, then I would say we'll never know but we can choose to believe that we see the same colors.

[@ggriffaw]

I tend to think some of our feelings based on colors are learned. For instance yellow, orange, and red are associated mostly with things that are warm and blue is associated with things that are cool. There are exceptions to both of those in reality but we are taught certain colors equate to certain things. I don't think that means we necessarily see colors the same, but for most people the different frequencies of light appear in the same sequence relative to each other so we can each react to whatever we perceive as a certain color in similar ways. There is no way to know if what your brain perceives as yellow is the same as how another person perceives yellow. Obviously people with various levels of color blindness will have a different perception because they don't have as much differentiation between certain colors or certain colors aren't as vivid. I would think this could make certain colors appear to be different than most people would describe them. Some animals can see frequencies of light that humans can't. I imagine there is some variation in the frequencies each human can see similar to how hearing varies from person to person.

[@fengmainbigbrain2291]

i think we kinda have to see the same colours. else for some people, fashion wouldn't work. or animals that have their colour because of nature to hide better would be more visible to some people than to others. or that we have warm and cold colours. it would be different for a lot of people so i don't think we'd be able to agree which are warm and which cold.

[@nickeni3050]

@@fengmainbigbrain2291 what if what we see are different in the sense that, the cool colours in my eyes don't exist in another person's? Like there are many cool colours but the ones that everyone sees is different, and same goes for warm colours... What if the colour blue looks like a different color of the same wavelength, shade and tone for every person? How do we know that humans don't see a wider range of colour than what we think? Imagine if by research every human can see 50colours, but the catch that we don't know is that everyone sees a different 50 colours from other people

[@masscreationbroadcasts]

I was expecting this to be something cheap like UV light, but no, no, you did deliver.

[@MichaelDHead]

I'm sorry, but you're wrong about light being black, mostly. In your first experiment, you are not seeing black light coming out of your phone, you are seeing the limited dynamic range that your camera is capable of recording - the dynamic range is the difference between the lightest and darkest part of an image that the camera is capable of recording without losing image detail due to overexposure or underexposure. When you turned on the softbox, it was so significantly brighter than the rest of the image that the camera's dynamic range was not capable of recording the white light from the softbox at the same time as the white light from your phone - which is why the entire image (your garage, I think) also became darker. The camera was automatically adjusting either it's aperture or gain to match the exposure of the softbox compared to the rest of the entire image, phone included. If you had a camera capable of recording a higher dynamic range, you wouldn't see your phone screen go dark, or if you turn off the auto correction of your camera. Your projector example is also incorrect because cheap projectors do not project black, just various shades of dark grey. This is the "contrast ratio" of the projector, which all projectors list. Like dynamic range, the contrast ratio is the difference in the brightest and darkest part of the image that the projector is capable of projecting while retaining image detail. It will always be projecting something, and what we see as a black part of the image actually only appears black when compared to the rest of the image - which is why you see a shadow when you stand in front of the projector. More expensive projectors have better (higher) contrast ratios, but they are more expensive. This is also true for projectors at movie theaters, but they are much more expensive because of stronger image projection, much better contrast ratio, and much better color projection capabilities. You are right that color is how we perceive light reflected off of objects, and every person perceives color slightly differently. But we can talk about colors because we have a common understanding of what different colors are, even if we perceive them slightly differently. Grass is green, for example, and we all agree on that. As for black, it is true that subtractive color is different from additive color, but you have to understand why we see certain objects as certain colors. In grass, on a simplistic level we perceive it as green because when white light hits the grass, it absorbs the other color wavelengths in the white light and reflects mostly the green spectrum of visible light. The same is true for red - red objects absorb other parts of the visible light spectrum and reflect mostly red. You can demonstrate this by lighting up objects with colored light - if you shine only a red light (no other light source) on a red apple, you'll still see a red apple, but if you shine a completely green light on a red apple, the apple will appear black - not because it is "shining black", but because it is absorbing the green wavelength light and not reflecting back the red wavelength because it is not present to reflect (on a simple scale - there will be a bit reflected because light of a pure wavelength is very hard to produce, especially on a budget). One side note - scientists have developed a black material called "vantablack" that is made from carbon nano-tubes that measurably absorbs almost the entire visible light spectrum, meaning objects covered with vantablack do not reflect back almost anything in the visible spectrum of light. Black is not a "shade" of white. TL;DR: Look up dynamic range, contrast ratios, and reflected wavelengths of light.
