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
moron
2:51 according to my video game experience, a new stage is going to unlock lol
That's how RGB display works...
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.
@@ciencialogica7783 What are you trying to say
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 ruclips.net/video/V5PEvzGwHHw/видео.html
@@ciencialogica7783 I mean't what is your point... Also i cant understand your english
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.
Yay! Another ActionLab video! I SO look forward to these, love this guy!!!
Zebra colour.
Edit:
Well, at least I was half right.
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!
Thank you so much @ActionLab I knew this thing for a while but never knew the real reason.
Thank you so much.
Yep that was a lovely video already watched it all.
I agree 💯
Thanks for clearing my doubt 😀☺👍
I hate when people confuse additive and subtractive color mixing. This video sums up their differences pretty well. Good job!
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.
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'm only 11 but i watch your videos and i guessed the question right.
This is how many people like The Action Lab.(BTW love ur videos dude)

2 million people... That's a lot of people to reply to
Ooooofffffff
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 totally guessed that it would be additive colour mixing because although liquiditive, it is light so it is white light but with a red tinge
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
Where do glow sticks get electricity lol
Is it just me or is that one of the most visibly satisfying thumbnails
Action lab just rocks
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
You guys are smart AF
@@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.
Lol, it was easy to guess because you‘ve mentioned it in one of your previous videos.
wow, very interesting! now to go get some glowsticks :)
Great video! You should use the polls for the guesses though.
You should do a video on scuba diving and light filtration through water as depth changes.
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)
My guess: I dont think the liquids will really mix but it's going to produce a white-ish light.
I guess I wasnt completely wrong.
Zimberg was my guess
I was thinking that it will produce white light, but when the glow effect will stop working, it would become 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

@@radicalxedward8047 wow
🏆🏅 These are for you, Sir.
For being correct, online, in current year! 👍🏼
i appreciate this comment
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

What’s the color of the liquid residue (w/o dye) after its glow is finished?
The white glowing color reminds me of The Vex from Destiny
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.
That's my childhood doubt!!!!!!!! Thank you
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.
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?
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.)
What colour would it be after it’s finished glowing
What's that liquid can we make that home did u put neon glow paints ?? Plz do reply I want to experiment with my kuds too
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 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.
Reminds me of the chimera color "self-luminous red"
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 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.
Cool
Where i can buy glowsticks? (for example in chemics shop, or... Idk)
depends on whether the lights are on or off I'd say, and whether it's in a cup or on paper.
Wow
I think white but i'm not sure. I like the fun in this video you made.
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.
I liked the video. I was wondering why use green when you can use yellow as the primary colours are red blue and yellow
because then green would be impossible to display
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.
Here goes my guess:
It will produce a faint white light, but the liquid, with the lights on, will be dark.
Edit: ok, k was wrong😂
Can you mix 2 sub visible laser waves (lower than infrared) and have them mix mid-air to produce a color? see where I'm going with this ;)
So how do the make the color white for painting?
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.
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.
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?
Can things float using vacuum
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.
I would like to see you mix blue glow stick with red paint, or green glow stick with blue paint. Visa versa, would it be black or white?
White - as it emits light. Unless you shine much brighter light source at it then it will be black.

@@lh-qs1nr Well, the stars are good examples of black bodies:)
Stars behave approximately like blackbodies. But they're not black bodies.

You should do something on Goethe's concept of light.
Can you make a video of light quanta: blackbody radiation and the photoelectric effect?
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?
When you say Wow! with him at 2.23
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
Awesome awesome awesome…
Looks like a mad scientist mixing all of those lol
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
Alright I was wrong 🙃
where can I send stuff to you
how do glowsticks work
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
How glow sticks work?
I'm early! Finally!
what are the chances of him making the video of my current study of this topic
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
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.
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.
2:10 my guess is that it would be subtractive, so a dark liquid would be created. Since it is not light, but produces light?
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.
If emitted lights are directly added, it's additive and if reflected lights are added, it's subtractive.
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
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.
White
You kind of gave away the answer when you held all the glowsticks in one hand. It was white! :-)
