Yes it's true... In case of red LIGHT, it emits the red light itself In case of red PAINT, it absorbs the other two light(blue and green) That's why when lights are mixed additive color mixing takes place whereas in case of paint subtractive color mixing takes ( correct me if im wrong)
Great video! One comment about subtractive color: don't use red, green, blue. Use cyan, magenta, yellow. Cyan is the absence of red. Magenta is the absence of green. Yellow is the absence of blue. You can't use RGB paint/due/pigment to produce any color you want; but you can with CMY.
VSR007 have you consider RGB works well because light is actually made of only three kind of particles?, check the TRICHROMATIC MODEL OF LIGHT COMPOSITION, NOT ONLY OF COLOR.
Torm Endor exact like the explanation at the first minutes. The blue paint absorbs green and red light, the green paint absorbs red and blue light, the red paint absorbs blue and green light. TRICHROMATIC MODEL, the to apply RGB to light composition. Three kinds of photons. Weird? Yes.
Torm Endor take a look to this images, i know it is in spanish. But, a light spectrum is made of only three colors ua-cam.com/video/V5PEvzGwHHw/v-deo.html
Digital artists actually paint with additive colors while using RGB sliders to swap from colors, for example red+green=yellow, it's different to the oil/acrylic color mixing techniques, it's also a cool way to think about colors!
The way the glow stick works is pretty interesting. The chemical reaction that makes the actual light, for all colors of glow sticks, only produces ultraviolet light, which we can't see. Another substance is added to the mixture that absorbs the UV light and emits light of a different color. But there's demand for all sorts of colors, and it's not always cheap, easy, or possible to obtain substances that will glow that color from UV. So for those "hard to reach" colors, I substance with approximately the correct color is chosen, and then as demonstrated in this video, sometimes a pigment is added to subtractively produce the desired color. This is part of the reason why some glow sticks, before they're activated, will already appear to be a certain color while other glow sticks' colors may be difficult to determine until they are activated. The ones that needed the pigment give you a "hint". Fluorescent bulbs work the same way. The metal vapor in the tube produces UV light when current runs through it, and the glass is coated (on the inside) with a substance that absorbs the UV light and emits visible light. So it's actually "simpler" to make a black light than a visible fluorescent light, because there's one less step. There are also "white" and "warm white" LEDs that produce light in a similar way. For the most part, an LED's light output peaks strongly at a specific color (though researchers are working on that). As this channel has mentioned more than once, "white" isn't really a color you can point to on the spectrum. So to get white light, you can use multiple LEDs close to each other, each with a different color, or you can use an ultraviolet LED and "paint" over it with a fluorescent substance that produces a mixture of light to produce white.
oh you should explain this is not quite correct, or on the other hand you should explain the system a bit more. Adaptive and Subtractive is totally right, but its in red/green/blue in one case and Cyan/Yellow/Magenta in the other case. these are the primary colors depending on the System, meas you can't create them with mixin two other together. On a Circle of Color the Color sit in between each other. So you use green Colour(dye) green contains actually Blue(cyan) and Yellow. Please try to explain this in some new episode. Thanks for you Videos.

I think white light because I assumed glow-sticks to produce light by passing electricity through a particular chemical, and when you mix chemicals together, it's additive
If the glow sticks aren’t mixed much I would think they’d produce white light, but since it’s a chemical reaction, there’s too many variables if they’re really mixed together. They could produce no light for all we know. Edit: I would basically call this right. It did produce white light AND there was an extra unknown variable of the red dye.
How is it a chemical reaction when there's no product no reactant and nothing reacts, the chemicals give off photons based on electron excitement and they would do that even if they were mixed at least that's what I think... Nice way of putting it tho
@@krishnarajthadesar6783 here's a question then, i probably could just Google it but I wanna hear what you think, glow sticks work by breaking the 'bubble' of x chemical thus releasing it into the other chemical which the two then produce the desired color. Now if all that chemical does is cause an electric reaction then y'all right and this entire ENT was pointless.
my guess is that it is going to be additive and produces white light because anything that emits its own light is working like so: it is EMITTING red, green, blue lights so we have white light, it is not absorbing any colors for there to be black
My guess is that it will produce an off white light? We can't perfectly balance all three liquid quantities perfectly nor can have we accurately accounted for varying intensities of light, so that's why I'm guessing off-white
The liquid will be white, because light is coming from the liquid not reflecting off of it. with paint, light must come from a source hit the paint and reflect what isn't absorbed, so adding more paint will add more light that is absorbed and isn't reflected. with something that emits light, the more colors of light you add increases the amount of light emitted(reflected in the case with the paint.)
Before you mix them...my guess is its not gonna be either. For some reason I think its gonna be orange. Edit: Well now I feel like a dummy. Lol Can you do a video explaining how colors reflect/absorb different colors?
I've always wanted to know why that was - very cool demo! Another related question I've always had is why are red, blue, and yellow primary colors of paint/pigment, while primary light colors are red, green, and blue. I am guessing it has to do with the additive/subtractive aspect, but I can not intuitively resolve that.
I guess while the lighting effect is operational it will be whitish (based on the correct portions of liquid mixed). Then as the glow effect wares off it will become brownish like normal paint.
Hey Action Lab! I don't know if it's with everyone, but this weird thing happens with me wherein whenever I cover my phone's loudspeaker while listening to audio, my ears feel a pressure, as if I'm on an airplane!
I really enjoy the way you tackle questions and not just answer questions but show and explain them. I thought of asking the internet but thought I'd ask you first and this seemed to be the right video for it... Light had to enter the eyes for us to see whatever is reflecting or emitting the light, but where is the light that is viewed thru a telescope? Has that light already reached Earth and we're magnifying it, or does the telescope somehow transport us to the light or reduce the distance the light had to travel to reach our eyes? Just wondering. Thanks for the entertaining videos.
I think it will be some weird third option that will surprise everyone and then he'll explain why Or maybe it'll just be white and what everyone expected, but I don't think it'll be black
Different phosphors will have different rates of absorption and emission. The phosphors that emit lower frequency light may fluoresce from light from the other phosphors. These may cause the color to deviate from purely additive.
It happened as i thought it would, the red stick was much darker, so i expected that to change the overall mixture to a pinkish color, but if the red was made the same way as the green and blue, the combined sticks would be white. Like in pretty much every digital display out there.
Anna( brother) do edwin lander black and white slide ( one slide is taken with red fliter and another just black and white). But after mixing two slides it will different colours. From walter lewin videos
Litterally prooved my comment from last video and that is that green and blue produce cyan and combined with red it makes the whitest hue of pink, but also, green is not a base color
I guess it's additive color mixing. The colors from the glow sticks are not being reflected from some other light source, they are being emitted, so mixing them together wouldn't stop the emission of light from each individual component. That is, unless there is some sort of reaction between the two chemically, which could potentially add another variable as such. But I don't think that's going to happen.
I'm guna go with a white liquid... Although in saying that i believe it'll only be white as the glow works otherwise it'll turn a weird black afterward
I think it depends on how those glowsticks function: if there white light shining on to colored liquid it's subtractive color. If the liquid itself is glowing in the color, it'll be additive color. So my guess on how those glowsticks are engineered is with a white light -> My guess is subtractive color
You mentioned that the red glow stick contains red dye. What about the blue and green ones? Don't they have dyes? If they don't, what will happen of you do add green and blue dyes to balance out the red dye? Will it be subtractive (since they're dyes) or additive?
I have discovered something and I can't figure out why it happens? If you take a wick and slide through a very narrow circle (imagine a paper clip stretched out straight, take needle nose pliers and twist the tip of the clip around the pliers till makes a, very small, complete circle. Like a small headed stick man without arms, lol!), and light the wick, when the flame gets to the circle, it slowly dies, rather than just continuing to burn down the wick. Why does the flame go out? There's fuel (the wick), there's oxygen, and there's an ignition, what is it about passing through the circle that puts the flame out?
Im guessing it will glow kinda whitish (though not completely), but the liquid itself might be brownish or greyish? As a side note me and my brother one day had a lot of glowsticks in different colours, and we opened them up and splashed it all across the walls in the bathroom...my mother was furious...until we turned off the lights and the bathroom wall turned into one of those NASA space photos that has been enhanced with colour (which is like all of them, heh). Was amazing. (We used those thin, party-sized ones though, not these "survival"-use types) EDIT: I was at least a little right? :3 EDIT2: Ooh, looking at the liquid when it seems to have stopped glowing so much and the light is turned on it kind of looks a bit reddish-brown, or well, reddish at least.
The idea is spreading it thin on paper, so that the liquid absorbs less light, but still the liquid in the cup was translucent enough to emit light and appear much brighter than the red stick.
If the liquid itself is colorless and emitting colored light, then it will be additive. If the liquid is colored and emits white light, then it will be subtractive. Which of these is a glowstick? No idea, but I *think* that when not activated they are still colored, so I'm gonna go with subtractive. EDIT: Huh, so it's a mix of both, depending on the color of the glowstick.
I guessed correctly that it would be white, but not pure white. I didn't know about the dye, though, so it was a bit more off than I thought, and once the dye was nullified, it was closer to pure white than I thought, probably because of how the dye affected the red glow stick, making it look a bit off from pure red.
It will give off white light. This is because the chemical mixtures within the glowsticks are producing their own light, not reflecting the light from another source. It is a clever experiment, one way or the other. Nice setup too, you may have thrown off some people showing subtractive mixing beforehand.
Why doesn't the argument work in the opposite direction? If the red paint reflects the red light, blue paint reflects the blue light, etc., then for each of type of light (red/green/blue) there should be molecules in the mix (red+green+blue paints) that reflect exactly this type of light? I.e., why do we have to focus on the absorption aspect and not on the reflection aspect (which would've resulted in white, as shown above)?
I am 13 and and I love science so much. Especially astronomy... Can you suggest me what to upload on my channel plz... That should be interesting and related to science and what people will love to see...
But what if you add green and blue pigment to glowstick red dyed white glowing liquid? The pigments should make black, but the liquid should stay white!
So I finished the video but my guess was that it was gonna fool you and stay as 3 separate colors due to densitys of the glow stick liquid. I was wrong, this is a really cool way of showing how the idea of RGB works. Too bad the red is pigmented, that beaker would have been awesome if it just glowed bright white.
Dyes and inks are subtractive color mixes, but paints can behave in ways that combine additive and subtactive characteristics, because they contain particles that reflect light of particular wavelengths. if one mixes yellow and blue paint, additive theory would suggest one should get white, and subtractive theory would predict black, but the actual result is green, even when the blue is genuinely blue and not cyan.
thx for this video. color & light are very fascinating. can you make an ultraviolet or inferred..or other light spectrum kaleidoscope? Also, a series on the periodic table would be great...perhaps start with the everyday metals we might not know much about...like chromium(someone told me is the only metal both magnetic & not, in its solid state)
I'd love to paint my chocolate in the toilet with the liquid light Btw interesting video as always and I wanted to ask something I know this doesn't make really zhat much sense, but would it be possible to make a reversed light/black light?
I think one of the video of him shows that if the light emits from that combination is brighter than background light then it'll show black right.... Is this might one of the reason for seeing black colour when we mix RGB?
well i thought it would give white because i thought in the rainbow effect with light and water! so in my head if the water have all those colers inside and dont make a dark tone but a lighter tone in the sky that means that if i mix 3 of them should give me something close to white! it could be a stupid thinking but at least got it !
But the glow stick liquids themselves don't directly produce R/B/G Light right? So it must be pigments or coating? If it were pigments then we get black, if it is because of an outer coating then we should get a white liquid. I am assuming it is coated so I am guessing a white liquid. Edit: Nvm, I guessed right but the thought process was wrong.
Additive light mixing - So it will be white. However, knowing glow sticks - I know that the color of the liquids are different too. The blue glowstick has colorless liquid. The green has green liquid. And the red has reddish color liquid. So assuming the light must travel through some of the liquid, I'd say that actually, it will be a dull yellowish orange (based on the ratios of the liquids and their relative brightnesses)
I would think anything that produces its own light would generally be additive and anything that reflects light would be subtractive.
Yes it's true...
In case of red LIGHT, it emits the red light itself
In case of red PAINT, it absorbs the other two light(blue and green)
That's why when lights are mixed additive color mixing takes place whereas in case of paint subtractive color mixing takes ( correct me if im wrong)
Yep! 👍
was thinking the same
that's truly helpful

Reminds me of the chimera color "self-luminous red"
The mixture of all 3 glow sticks will produce a white glow since they're emitting light instead of absorbing light to produce the color.
I thought it would be black but shine white light. Does that make sense?
It would make sense if they all emitted white light, but then used dyes to determine the color... but they mostly don't work that way.

Dyes and inks are subtractive color mixes, but paints can behave in ways that combine additive and subtactive characteristics, because they contain particles that reflect light of particular wavelengths. if one mixes yellow and blue paint, additive theory would suggest one should get white, and subtractive theory would predict black, but the actual result is green, even when the blue is genuinely blue and not cyan.
Can you explain the cold welding?
thx for this video. color & light are very fascinating. can you make an ultraviolet or inferred..or other light spectrum kaleidoscope?
Also, a series on the periodic table would be great...perhaps start with the everyday metals we might not know much about...like chromium(someone told me is the only metal both magnetic & not, in its solid state)
I'd love to paint my chocolate in the toilet with the liquid light
Btw interesting video as always and I wanted to ask something
I know this doesn't make really zhat much sense, but would it be possible to make a reversed light/black light?
What I understand by "reversed light/black light?"
@@babyyoda5074 I mean a "light", that doesn't light everything up, but makes everything darker, something like a shadow emitter
@@mega3050 damn, I can't imagine that lol
Wait
Wouldn't shadows fit for that criteria? I mean it's the opposite of light
You kind of gave away the answer when you held all the glowsticks in one hand. It was white! :-)
What is the glowing liquid actually?
If you shine a light brighter than the light being emitted by the liquid, would the liquid be brown/black?
can there be something like dark light? I mean something like a black coloured light
I'm guessing it will be white light, since the three colors are emitting light, not absorbing other colors of light.
Well, I wasn't quite right. But it was definitely a lot whiter.
I guess it will make a glow-in-the-dark black paint, that is normally black, but glows white.
Can things float using vacuum
I think one of the video of him shows that if the light emits from that combination is brighter than background light then it'll show black right.... Is this might one of the reason for seeing black colour when we mix RGB?
If emitted lights are directly added, it's additive and if reflected lights are added, it's subtractive.
Yay! Another ActionLab video! I SO look forward to these, love this guy!!!
what are the chances of him making the video of my current study of this topic
Why is it, that when you mix paint to be black, the "reflect" doesn't get mixed, but the "absorb"?
I guess White, because it is produceing light, should be additive. But with chemical reactions mixing i am not 100% sure. I like your aproach to RGB
well i thought it would give white because i thought in the rainbow effect with light and water! so in my head if the water have all those colers inside and dont make a dark tone but a lighter tone in the sky that means that if i mix 3 of them should give me something close to white! it could be a stupid thinking but at least got it !
But the glow stick liquids themselves don't directly produce R/B/G Light right? So it must be pigments or coating?
If it were pigments then we get black, if it is because of an outer coating then we should get a white liquid.
I am assuming it is coated so I am guessing a white liquid.
Edit:
Nvm, I guessed right but the thought process was wrong.
Additive light mixing - So it will be white.
However, knowing glow sticks - I know that the color of the liquids are different too.
The blue glowstick has colorless liquid.
The green has green liquid.
And the red has reddish color liquid.
So assuming the light must travel through some of the liquid, I'd say that actually, it will be a dull yellowish orange (based on the ratios of the liquids and their relative brightnesses)
Wow - my guess was way more accurate than I would have guessed.
I feel pretty impressed with myself right now haha.
