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?

    Pigment (or really anything that absorbs/blocks light) is subtractive color. CMY(K) is commonly used in printing, but you could just as easily use RGB pigments instead.

    There’s a reason CMYK is used for printing. How are you going to mix RGB pigments to get yellow? R+G won’t work. That’s because red ink filters out green and blue light, and green ink filters out red and blue light. So mixing the two you get something that filters out a bit of everything but especially blue, ie. brown. CMY are used for subtractive color mixing because each one filters out just one of the colors we see (C filters out R, M filters out G, Y filters out B) so you can mix them to get most of the gamut you need.
