Fun fact, most cameras can pick up near-infrared light, which looks purple in video. This is probably why there is a purple spot at 3:41
+FreeDoum Really?? That's cool. I also had some issues recording the red light in a uniform way.
so thanks to VSauce3 and TH-cam community, I have found you. I'm currently studying computers a my mathematics class is practicing binary and hexadecimal. color me impressed and subscribed. (all the puns intended.)
That sounds awesome! I also have a video on base number systems I uploaded right before this one that you might enjoy. I can't think of a color or base-number system pun right now but I'll be back.
YES
Thank you for talking about proper color theory! I hate the way we teach color in schools.
Yeah, I didn't even know it was wrong until I started looking into all of this.
Everything makes so much more sense now
At school, I'm part of theater tech; wherein I help construct the set that the actors perform on.
My favorite part of tech has always been lighting design, and in particular color theory.
Going through the process of mixing the colors of the lights with the colors on the set to create a specific effect (such as a light redish color during a romantic scene or a cool blue for nighttime scenes) just gives me a lot of pleasure.
It's something that most audience members won't notice (and they shouldn't if I do my job correctly), but in my opinion, it's the single most effective thing at adding to the atmosphere of a play.
That is very cool! I'm guessing you have the option to tone down the intensity of the lights, too.
***** Indeed.
Color and Light was one of my favorite courses way back in college. Thanks for the memories! :)
+UatuOmega No problem! This stuff is fascinating.
this guy's a fucking genius like this legit blew my mind thank you Vsauce3
Thanks so much. Even though I knew a good chunk of the video already, I learned some more things (additive and subtractive colors) that will further my understanding of colors.
glad it helps!
Found this video in my recommended this morning and found it pretty interesting. It was a lot more useful to my roommate however as he is in a Digital Logic class this semester and everything in his homework with hex code suddenly makes sense. When the professor cant make you understand it always helps to look it up on TH-cam.
+christiaan jansen Glad I could help him out :)
I'm color blind but I find this fascinating! It intrigues me a lot! But it's still kind of abstract haha. Just found your channel because of Jake, you just won a new subscriber. Awesome work man! :^)
Thanks! And glad you were still able to appreciate it :)
So useful! Thank you！
Very interesting. Despite my job being quantum mechanics, I didn't know this about light. And you explained it all so succinctly and elegantly. Very clear! Thanks!
+Geldarion Degana (The Fanatical Swordsman) Glad you enjoyed it!
The Anonymous Sexual Redditor programming, data entry and analysis, lots of reading, occasional travel to conference, and writing.
Deadly video! I never realised the meaning the hexcodes actually have beyond just seemingly random digits lmao. But yeah Karen kavetts colour theory videos also go in about tints shades and hues as well as complimentary colours. I remember on a physics test earlier this year one of the questions was name a pair of complimentary colours of light and I was the only one to get it because everyone else was thinking in terms of subtractive (ryb)
+randomliamsquares765 Haha nice. Yeah I'll have to check out her videos since I know someone else mentioned her, too
I wish I could 'like' this video more than once. Brilliant explanation!
+Stefan Szczygiel thanks!
Vsause3 sent me here
and I don't regret coming
You are awesome! Plz keep doing what you're doing
Aw thank you! I plan to :)
So glad I found this!
I'm glad Walt Jr wasn't affected to much by what his dad did.
+Robert Price It was a poison apple. It had to fall far from the tree.
This video is great! I wish I had come across this way before!!!
I love you never ever stop!!
I SHALL NEVER!
This is high quality stuff!
wow, interesting, actually amazing!!!😁
way cool! I love videos like this.
way cool! I love comments like this.
Ah, some more comment. I think, light mixing and colouring occured at several points of time to me in school:
First in kindergarten/elementary school in art class,
then in physics class in about 7th grade (additive/subtractive colour mixing using prisms and different light sources),
in physics class when the wave-particle-duality of light was discussed (around 9th grade and again in 11th)
and in chemistry class when we looked at indicators (9th or 10th) and again when looking at aromatic hydrocarbons and their use as colourants (11th or 12th).
+Elchi King (Maddemaddigger) I feel like whenever I make these videos I get so many comments like this where people say "yeah I learned this in school!" And then I get jealous because your school was clearly cooler than mine, haha
A note on the imperfection of paint. a lot of especially cheaper paints add a neutral or white colored filler such as aluminum stearate. This changes what is known as the tinting strength. What ends up happening is some paints have more or less filler, meaning the amounts of pugment in equal volums of paint aren't equal, resulting in muddy colors.
+YouCanScienceIt interesting, I had no idea! Now I really want to see if this would work even if I had the exactly correct paint.
the first time i heard somone say green+red=yellow and i am now aware you are correct
Great Video! Informative.
thanks!
Such a great video for someone so small!
Aw thanks!
that was so cool how u guessed the colors buy I wanna do that too how can i learn which numbers refer to what
who is here from vsauce 3?
I am
Did he upload a video mentioning this/me?? I genuinely have no idea haha
Just saw the community post. That was so nice of him
John Green, actually!
Matthew Jensen I am
Love the Bruce Shirt! Just saw him on The River tour...
+Technicality DUDE I LOVE HIM! He's coming to Penn State but I don't think I can go because I have a pre-concert practice with my a cappella group :(
Great video! Nothing is better than truely understanding something new :) thank you!
+Jente Kramer glad you enjoyed!

Wow you are a genius! That hex game though! Bravo
It's easy if you learn hexadecimal :)
How can I get colours in hexadecimal?
Great video, I love hex color codes. I'm still not sure how 1F is equivalent to 19 or F3 being equivalent to 93. I know there's a logic to it, but I would have loved to see more explanation into how that works in your video.
+Dan Xander Hexadecimal uses base 16 it goes 1,2,3,4,5,6,7,8,9,A,B,C,D,E,F so 1F = 16+15=31
+Thel 'Vadamee Awesome, thanks for explaining it! I just went back and watched his Base Number Systems video, so I get where he was going with all this.
+Dan Xander I think the point he was trying to make is that in base 10, the last digit is 9 and in base 16 the last digit is F, so F is like 9.
+David de Kloet ^That is exactly correct. I was saying that if you were to write an approximation of this value in base 10, it'd be like 90-ish.
+Dan Xander It doesn't actually equal those numbers, but if you don't understand non-10 base systems then it's a good way to think about it. FF is the full value, or 100 from a scale of 0-100. 00 is the empty value, or 1 on that same scale. So something like F1 would be roughly equivalent to 91 (because 9 and F are the highest possible numbers in that digit. On a scale from 0-100, F1 is actually ~94.141). 1F similarly has the first digit as 1 and the second digit as the highest possible number, so in base 10 it'd be 19 (though this one's a bit more off, the base 10 equivalent is ~12.11.
Thanks for the help.
+JoMaMa 66 💪💪💪
No problem
loved it
Hopefully you've figured this out since you posted this, but I believe the issue you were having with the camera picking up colors is your camera's white balancing and exposure metering. If you want the video to be true to the colors you need to set your camera to manual and adjust the parameters to the room and leave them fixed. Your white balance (color temperature) should also be fixed (probably to 4,000K if you have fluorescents). That's why the colors keep changing when you add different lights (ie the blue light started off as purple but changed to blue when you added a red light). Leave nothing automatic! Fantastic video, regardless of the WB issues
The colors, Duke, the colors!!!!
Thannks dude...i was able to understand a lot... :p
In most modern browsers you can also specify an alpha channel by using three integers between 0 and 255 for red through blue and a floating point number between 0 and 1 (1 being opaque) for the alpha channel.
It looks something like this rgba(255,100,255,0.5) I don't think there is a hex equivalent of this though.
This also works without an alpha channel by doing rgb(255,100,255) would be #FF64FF in hex.
+MrC0MPUT3R I've actually seen this in HTML/CSS code, though I have yet to try it. Thanks for sharing!
great video
+Sparky 14 great comment
Can someone send a link to a video where I can learn how, for example, F1 is seen as 19. Completely green in this whole thing but I'm really interested in Hex codes. Please help :)
Sorry for a little late, but
So the way we fit 0-9 into one digit in base-10, in base-16 it goes 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F where F is the highest possible number for that digit and 0 is the lowest. So that's what I mean when I say that F1 is kind of like 91. FF would be kind of like 99. It's not perfect, but just a way to think about it for those who might be stuck. Hopefully I didn't confuse more people than I helped, haha
***** Thanks! It did indeed help a lot!
okay, what i did not understand is why does it make sense to use hexadecimal, since the value represents a fraction or a percentage anyways? why not any other numbering system?
I'm guessing it's because computers are mixing the colors, and computers understand base 16 well because they think in binary (base 2) and base 16 is 2 to the fourth power. That's just my two sense, and I'm not very qualified, so if anyone else replies with something different, they're probably right. I just know a lot of computer stuff is base 16 because it's a power of two.
+Margaret Madole you're right. for a computer, FF (255 in base 10) is the higher number you can reach with 2 digits. it also happens to be exactly one full byte (11111111 in binary), and computers are crazy efficient when storing and computing bytes.
and we use hexadecimal, because binary is terrible for humans?
well saying it happens to be is a bit weird because it obviously is since (16)^2=(2^4)^2=2^8
+Felds Liscia This is awesome. I didn't even think about this.
ok well that's how is normally explained though if one studies how the "cones" in eyes work you will find its even more complicated.
Wait how did I miss this video??? OK let me watch it.
+Lorenzo van Breda lol
First! :)
Interestingly the hexadecimal is used because Hex is a way to represent binary with far fewer digits.
F = 15 = 1111(Binary) so the four digits in binary can be represented by a single hexadecimal character
+mathphyskid ooh, cool! didn't know that :)
+mathphyskid though I guess it makes sense since the system is (binary)^4
i got anxiety when the hexadecimal code under the sliders became blocked by the message. i felt lost and like i couldnt guess the color.
+envy nine haha that was intentional ;) You can still guess what percentage each number represents and slide it accordingly.
***** thanks for clearing that up and replying! i like to add replies of my favorite youtubers to a g+ collection, but cant cuz of your channel settings :0
Coool!
Whooo!
uhh hmm so this explains hue.......now i wonder how saturation and tones fit in here
for example tones is how much white and black you add to the mix uhhh yeah hmmm
Makes sense. White paper would do better with CYMK.
Or you could paste "document.getElementById(document.getElementById("target").innerHTML).click(); window.setTimeout(partB,1000); function partB(){location.reload();}" into the console and hit enter...
Cool
Thank you
2:47 but those two are not same green 🤔
You should use some soundtracks, those make a lot of difference ;)
I'm thinking about it. I've used music before and don't like it but I don't always like it without music either.
Hey Matt, I remember you saying that you played smash in one of your videos. Which smash game do you play? Also who is your main?
It'd be pretty cool if you could do a video about science or math and relate it to smash in a way.
+SirMisteryYT I actually plan to do that in the future! I play all of them, but in a competitive sense I mostly play 64 (and I main falcon there)
Nice. I'm more of a melee player myself, so I'm not completely familiar with 64. Good luck trying to get better!
+SirMisteryYT If you search the channel "Filet 64" you'll find a second channel of mine
*finds this chnnal today (now I'm obsessed)
+awlom thesheepermen yay!

It has to be said that color and color mixing is not something that exists in reality. It comes from the fact that we have 3 types of cones (light color receptors) in our eyes: cones that mostly see red light, cones that mostly see green light and cones that mostly see blue light. That's why we call red, green and blue the primary (additive) colors. If we had different kinds of cones or different color perception altogether, colors would work in a completely different way. And yellow light is actually different from red and green light mixed. Our limited eyes just can't see the difference because we don't have yellow cones.
+David de Kloet Oh yeah I know about cones. But even though our eyes only process Red Green and Blue colors, I feel like that doesn't preclude the possibilities that colors can effectively "mix." Or are you saying that light mixes but physical color, subtractive mixing, is just something our eyes show us?
right and wrong. yellow does in fact exist in nature: it's a measurable electromagnetic wavelength (unlike pink. that one doesn't exist. look for the Minute Physics explanation). the thing is that the color yellow excites our red and green cones a little, just like the separate colors also do, so it's exactly the same for us, even though red and blue don't physically mix and become one.
+Conjecture Hey, btw. there are some other ways to generate different colors, like e.g. using chemical reactions. But espacially in acid-base-reactions with indicators you can see subtractive color mixing: Bromothymol blue appears yellow when it is solved in acid, blue when it is solved in basic solutions and "green" in a neutral solution.
And an example for a chemical reaction in order to get a color is coloring cloths with indigo in the way it was done 100 years ago (e.g. with jeans): They apply an "uncolored" solution on the cloth and then let the air oxydize it. In this process, the color will become blue because the chemical structure of the coloring molecules changes...
***** you can mix colors but it will not become one new color. It stays a mix. If you send true yellow light through a prism, a single beam of yellow light comes out on the other end. But if you send a mix of red and green (that looks like yellow to us) through a prism, it will split back into a red and a green beam. So you could say they didn't really mix.
In the same way, different musical notes don't mix into a new note. A chord will always sound like a chord and not like one other single note.
David de Kloet Hm, but a flute does not produce exactly one tone, there are (in theory) infinitely many overtones which make what we identify as "one tone". While in theory one tone is exactly one frequency, what we hear as "a tone" is most likely the bass tone reconstructed by our brain. (Which is the reason why e.g. shepard-tone-illusions work)
we guessed the same color's! lol!
255, 0, 133?
Interesting, I find additive colour mixing way easier than subtractive, but hexidecimal is still beyond me.
+Blake Hagar Even after this video? Very easy! Just like RGB additive mixing but with values for the amount of R, G, and B
***** Honestly I have never really spent the time to properly understand it. For some reason additive just comes more naturally to me. It is probably worth learning tho, both are useful in chemistry for some reason I can't really remember aha...
Blue and green may be aquamarine
Is your inspiration Vsauce? Not to advertise, but I find your..."style" sorta like Vsauce... (Which I like, so good job 👍🏻)
I think it's a great mix of vsauce and the vlogbrothers
+Cali_ Girl97 He did make a parody of vsauce, CGPGrey and vlogbrothers.
+Cali_ Girl97 I wouldn't say he's my sole inspiration, but he's one of them. I think at this point I'm a blend of my uniqueness and others' inspiration more so than I'm derivative of one specific TH-camr. But if I had to pick one creator of which to be most derivative, it'd be the vlogbrothers :)
+Conjecture well, I'm glad that you have your own style :) a lot of people on TH-cam copy others... It's nice to see someone who,doesn't
Vsauce 3 anyone.
Very interesting to learn! However, I don't think I could ever memorize the code! XD
+Saenae Chan it's not that bad! The more time you spend with it the easier it gets :)
+Saenae Chan Actually, for an approximation, it should be sufficient to memorize two things:
a) The first two digits represent red, the next green and the last blue.
b) you only need to look at the first, third and fifth digit (as ist has much more value than the second). Then you have a scale: 0 is least, F most (since you have 16 digits 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F, we can derive some "ranges": 0-3=low, 4-7=medium low, 8-B=medium high, C-F=high)
e.g. 0F84F0 should be a mix of almost no red, some green and much blue which would give approximately a "greenish" blue. (Actually it looks like the sky in summer)
Elchi King Thank you! I'm trying my hand at "What the Hex"!
+Elchi King (Maddemaddigger) yep, something more blue than cyan.
Awesome nerd punk
IMMMMMMMMMM just just a little confused at 2 mins in
Just a tip: Don't say everything you are doing like "had to re-record this' or "first let me explain what I'm talking about"
Also, talk a bit slower please!
Also, why do you say "blyack" instead of "back"
Also, great channel you have! I look forward to watching ALL your videos!
+Enig Matic Well I wanted to explain why my clothes changed haha. And I guess that's just how I say things.
I do my best to enunciate :)
Not sure, maybe the enunciating thing.
Thanks, YAY!
Guys is this for gta???
Lmao u was here to for gta

I just noticed that you have an accent with words with an L, like when you say blue or black or light. Or are you just doing that purposely?
+InfamousWolf1 Well everybody has an accent ;) However I have a totally normal, traditional American accent. That's probably just happening because I'm trying especially hard to enunciate haha.

who's here because of Jake?
wait did he tweet this video out or something?? I'm confused haha
I'm even more confused than before 😭

Now that you know colour, you might want to hit the white balance on your camera.
+steevf I actually know nothing about it. Can you share where it where it could have been better and why?
It's a colour correction setting on your camera. It adjusts for the variance in the colour temperature of the light. Right now I can tell your camera's white balance is set to a daylight or "natural" light setting because all of your videos have a strong yellow hue to them when you're on screen.
+steevf My camera was actually set to auto for almost everything...I should invest time in learning how those functions all work. Would it make more sense for my face to appear whiter?
+Conjecture some cameras have a button to get white balance done. You simply need to zoom onto something which should be white and let it do the rest (obviously, you shouldn't change your light afterwards...)
+Conjecture It's not really about your face being whiter. I looked at the video again and I noticed the first shot of you the white balance looked almost correct as the walls behind you looked white and slightly pinkish, assuming they are really white, but then later, in the next shot, the colors changed. You'll notice in the next shot of you there was an open window behind you. That light was much hotter and the camera was trying to adjust to it so you can see that the walls in you room looked more yellow. When you covered the window later, the camera seem to still be wanting to used the correction mode for when the window was still open.
And then when you were doing the colored light demo, I"m sure the camera was having a real hard time with that and it may have been why you were getting unexpected purple in the blue color.
The most interesting example was on your "end card" when you were mentioning the bad examples of color you found on the internet. You can see the different colors of light in the same shot split down the middle. On the right of the frame you had natural light, and on the left the room light. Noticed the color differences? That's what the camera is trying to adjust for. We don't always notice it as much with our own eyes.
Auto white balance settings don't always work because sometimes the camera will get it wrong. And cheaper cameras many not even have good while balance. But I wouldn't worry about the quality of the camera until you've leaned all of it's quirks and know if a better camera will actually fix things.
The one thing I learned over the years is that digital photography can be a color science all on it's own.
Nerd!!!!!
OMG YOU EVERYWHERE
Like if you came from vsauce3!
#FF0000
sadly because i'm colorblind.
magenta doesn't actually exist. do some research into that lol
what lol what do you mean
Conjecture the color does not appear in a rainbow neither is it part of the spectrum. it's a thing our brains made up so you could see that mixture of red and blue. but it's weird because they are on the completely opposite sides of the spectrum.
Vsauce 3 anyone.
