I'm sure everyone learned that Red Yellow and Blue were the 3 "master colors" that were said to make any color imagineable. At least that was the case in middle school art class. So, how did we end up replacing Yellow with Green and completely changing the universal standard?

Just about to post this; paint is different to light

It largely has to do with how we perceive color. There's two ways "color" can exist
1) It's emitted (like an LED). These are "additive" colors
2) It's reflected (pigments) "Subtractive colors"

>Traditionally, it have been used additive colors (RGB) because the canon for computer graphics was the computer monitor, and since it's a emiting element, it makes sense to use the same structure at the graphic card (the colors are showed without conversions),

red, green, blue are the primary additive colors
magenta (red), yellow and cyan (blue) are the primary subtractive colors

>Red Yellow Blue
I am a hobbyist color science and this is literally the first time in my life that I've heard somebody say “red yellow blue”.

Normal color systems are red green blue = RGB or cyan magenta yellow (black) = CMY(K).

I have no idea where you got into your head that Red Yellow blue was any sort of standard that anybody ever used in the history of ever

Have you fucking looked around you lately? The entire world is falling apart, America being one of the big driving factors.

SJWs and feminists are infesting everything, every month you hear about some new “free trade”, “IP protection” or “anti-terrorist” bill, obesity skyrocketing as people stopped giving a shit about food regulations etc. and all this is being exported straight from the arse of the american society to the rest of the world.

Granted, europe has it extra bad because we're importing shit from the west and shit from the east, but that doesn't make the situation in the rest of the world much better.

Pigment vs light , or subtractive vs additive.

In art class you use paint, a pigment. You can make any color pigment out of red (actually magenta), yellow, and blue (actually cyan) pigments. This is why everyone learned these as primary colors in art class.

Mixing light (think of pointing multiple beams at the same point), works differently. Instead of mixing different-colored substances you're actually dealing with the waylight waves add and cancel each other out. In this system, any color can be made using red, green, and blue. So these are the primary light colors. Because the pixels in your monitor work by combining light, this is the standard used in computers.

Both are valid sets of primary colors, depending on the situation.

I learned the same. But you expand your horizons when you get older. Remember when you could not subtract 5 from 4? Then you learned about negative numbers later. Same for colour systems.

I was just messing with you. Besides, negative colors are a thing

In software they're used to represent out-of-gamut colors

But your eye can also see a type of negative color (by overstimulating the cones and then looking at an opposite color): https://en.wikipedia.org/wiki/Impossible_color

>>55891176
Literally look at any color wheel ever.

Red, Yellow, Blue would be the primaries, and when you mix them you get secondaries (Orange, Green, and Purple, by mixing Red & Yellow, Yellow & Blue, and Blue & Red respectively)
Tertiary by mixing primaries and secondaries, and so on.
>>
>>55893089
yes, much better

p.s. I find it sort of questionable that wikipedia asks you for full personal information when making a donation. I have a feeling it's less of a donation drive and more of an information harvesting gig

The links are there for a reason mate. Don't make me fall for you bait again sonny.
>>
>>55893223
But our cones don't see in “red, green and blue” as the lines would suggest

M and L both see pretty much the same spectrum of color, and our idea of red and green arises from the relative difference between them (opponent color process)
>>
>>55893260
And reading through the first link will tell you this.
Yes, yes. With some subtle differences. All the same, the idea of a set of primary colours is entirely context sensitive. With some perceptual models primary colours don't even exist the way they most people think of them. Eg: Lab colour and spectrum based systems.
>>
>>55893330
Yes I know all of this. What I'm telling you is that the idea of coloring them red, green and blue is misleading

I say this because it that coloring in particular misled me for a long time when I was new to this stuff.
>>
>>55892680
This literally is only important if

A) its your job, as in you work in printing,
B) you are an artist.

There are far more important practical things you need to learn then this, so a once over when you are in grade school and then a physical science class is enough

>>55891176
dude what
RYB are your 3 primaries that anyone whos ever mixed paint and painted a picture will know
RGB refers to your monitor/display colour space and nothing more
>>
>>55893557
RGB is based on physics, the human perception of color, the wavelengths of light, etc.

RYB is based on some paint-sniffing guys centuries-old pre-physics ideas of how color worked

you're free to believe whatever the hell you want, but I believe in science

>RYB is based on some paint-sniffing guys centuries-old pre-physics ideas of how color worked
and thats exaclty how it does work, there is no Green primary, its made by mixing Y and B
>>
>>55893641
How fucking retarded can you get?

Spectral green is made by mixing yellow and cyan. Your “muddy” green primary will never be as bright as a spectral green would. You also can't mix cyan or magenta at all

enjoy your shitty paintings. I'm sure the entire printing industry has less of an idea what they're doing than some arts and crafts major
>>
>>55893530
>if i knew more about programing i would have

I can assure you it's important in GUI programming, game dev, web design, graphic design, and basically anything that involves a computer screen.

This entire thread. I've never even met someone who was ignorant about the differences of light and pigment coloring.

I mean don't you, inhabit a world governed by physical laws, with effects you can observe and internalize? There are people with working vision who never notice this stuff?

like i said, no idea about programing side of things, i don't know how much of the legwork is already done and its all people piggy backing off of what's already made.

I mean look at it this way, the people who programed unreal engine, i have no doubt they need to know that shit to get the engine functioning, but the people who use the engine afterwords?

If i knew more about the entire process and how much is piggybacking, i would say more but i don't.
>>
>>55893804
>It predates modern scientific color theory.
>This theory became dogma, despite abundant evidence that red, yellow and blue primaries cannot mix all other colors
>Using red, yellow, and blue as primaries yields a relatively small gamut, in which, among other problems, colorful greens, cyans, purples and magentas are impossible to mix, because red, yellow and blue do not correspond to the subtractive primaries dictated by human color vision.

tl;dr people who believe RYB is a valid color model are fucking retarded

If you're programming in ANY field and you don't know how to red a color hex code, you aren't a real programmer

sorry to break it to you

>>55893839
I think we are thinking of something completely different.

you are talking about picking a color
i'm thinking of creating the code to define what that color even is.
>>
>>55893861
my point is that if you understand hex color codes you understand it's #RRGGBB and therefore understand it's not yellow in the middle
>>
>>55891038

Take printed media

Who would think of cyan and magenta as "standard" colors.
>>
>>55893876
humans because that's how our eyes work
>>
>>55893715
That's the same thing the banks do when you pay wikipedia in a regular way.
>>
>>55891038
RYB is a painting thing that is old as fuck and keeps being used in plastic arts because of tradition, RGB and CMYK are primary standards based on how our eyes perceive light and paint (reflected light) aka additive and substractive colors, hence why screens of any electronic device are all on RGB but when you print, lets say, a poster, you're suggested to do so on CMYK so you don't have any issues with wrong colors (K being key or black).

Don't try to mix red, green and blue paints in real life, you will only get a shitty brown color and disappointment. Try doing the same with spotlights or lightsources and you will get white, though.
>>
>>55892872
Oh i know out politics suck. But i was talking about politics in General - especially American Politics.

I focus more into American than Australian, some Australian politics are real great. But we are better at judging them - where swedes and Germans vote whatever lets more refugees in.

And they will always feel guilty about themselves because they think the holocaust was the worst thing to ever happen in the world - just like how most Americans think 9/11 was bad.
>>
>>55891038
Because schools teach it wrong. Learn up color science, color gamut, sRGB and the likes.
>>
I'm surprised I can't find a scanned version of this. Anybody? This is pretty old but it's considered as a good base literature about colors.
