You don't "buy" it?
Authored by: stegu on Friday, August 24 2012 @ 02:26 AM EDT

You don't "buy" what? A solid history of color perception research and the thoroughly educated opinion of every color scientist on the planet?

Color reproduction (RGB, CMYK and other primary color sets) and color perception (color wheels, opponent color theory) are two very different things. One has very little to do with the other when you look closely into it. Believe me, I have a PhD in the field, and I teach this stuff, so I know.

To the human eyes, brain and mind, there are four primary chromatic colors, colors that stand out as unique to every human being who has normal color vision. These colors are red, green, blue and yellow. Which exact hues are considered "pure" yellow etc has been show by experiments to be very consistent across the human race, in fact so consistent that a color system has been built around it, NCS:

NCS is not the only color system based on color perception, but it is the one that is most solidly founded in perception research and does not confuse color mixing technicalities with color appearance.
