like if you wanted to mix paint to get a color from a computer would you do the opposite of what the RGB value is? I’m confused
like if I wanted to take the RBG code R:99, G: 66, B, 33 wouldn’t it look more lightful than if I mixed paint into 1 part blue, 2 part green, 3 part red? how would you paint a color code?
RGB is additive color, best for light emitting displays such as your phone or computer screen.
CMY(K) is subtractive color, the opposite/negative of RGB.
CMYK (Cyan, Magenta, Yellow, blacK) are used as standard printing colors, because they don’t emit light, they reflect whatever light that they don’t absorb.
CMYK = Cyan, Magenta, Yellow, and Key. Key is almost always black in the print world because printing 100% CMY comes out as a muddy almost black. Having Key as black also allows for better greyscale and higher definition over CMY alone.
K stands for key. Not black. Depending on the color of the stock the ink uses for the key could be white(on black stock.)
Fair point for non-white stock, gotcha.

Thank you for reminding me, that for some reason the industry decided to call the darkest color the Key color, my bad.
What is the Key color again? Oh, blacK?
Misinformation and confidently incorrect.
Print is always subtractive. Why don’t you look shit up before posting bullshit?
As opposed to the posters and paintings that shine, huh?
Wtf are you on about? Those are all like print in that they mix pigments that absorb light. That’s exactly what over_clox said. The contrast is with monitors or displays that emit light, like phones or computer screens.
They’re all subtractive in print.
The person said RGB is additive. Where in print is RGB additive?
Educate yourself https://en.wikipedia.org/wiki/RGB_color_model
Right back atcha bro en.wikipedia.org/wiki/Screen_printing
Can we all just chill out and have a good [insert time of day]?
Very interesting. Doesn’t use an RGB color model though.
Yes, I said CMYK print is subtractive, did you read my comment?
You’re close to getting it. You said RGB is additive. Where in print is RGB additive?
Quick crash course, we’re gonna ignore K for simplicity, and assume a basic RGB system. Okay, simplest conversion to CMY is…
C=1-R M=1-G Y=1-BI’m totally skipping over a lot of stuff here, but this is about the simplest conversion for example sake.
