User:Heyzeuss/Partitive color

Partitive color, optical, or retinal color mixing is a concept similar to additive color mixing, where different wavelengths of light strike a group of cones on the same spot on the retina. The retina has three kinds of cones that detect three respective wavelengths of light: long (L), medium (M), and short (S), which correspond to red, green, and blue. Whereas in additive mixing the colors come from the same spot on the same object, in partitive mixing, the colors come from adjacent spots. In partitive color mixing, the colors may or may not be diffused on the same spot on the retina, and when the light is not diffused on the retina, the colors can mix psychologically. In additive mixing, the mixed color is as bright as the parent colors combined, but in partitive color mixing, the brightness of the mixed color is the average of the parent colors.
