    The color people will tell you that cyan and magenta do not equal red and blue. My university advisor tricked me into taking a 400 level class from the college of art and design on color theory. Really interesting class but an insane amount of work. Very early on the professor told us to throw out any book that identified red, yellow, and blue as the primary colors. It’s red, green, blue for light or cyan, magenta, yellow for pigment.

      Red/yellow/blue are the primary colors for paints (as distinct from dyes/pigments, that’s CMY(k) and as distinct from light, that’s RGB).

        Why would paints have a different primary palette than dyes or pigments? They’re all subtractive, so the primary colors are CMY.

        The red/yellow/blue is a lie!

          Are you asking me why is paint the way it is? I don’t know, take it up with nature, but stop spreading misinformation.

            I’m saying that, with respect to color reproduction, paints work exactly the same as dyes and pigments. You can’t make magenta paint from red, blue, and yellow. So the “primary colors” of paint are actually CMY.

              Yeah it’s just historically been very difficult to make magenta and cyan paints so ryb has stood in for cmy
