Theoretical foundations[edit]

Mixing transparent dyes acts like stacking colored filters, because each dye absorbs complimentary colors rather than reflecting its target color. So the case for Divisionism is very strong for water colors. Particles of inorganic pigment tend more to reflect their target colors. So the difference in luminosity between divided and mixed colors is less with oil paints, vanishing at least in the limit of large opaque pigment particles. "Interact optically" may be misleading. It is here used to mean that colors mix in the eye or in the brain, but this is not really an optical effect. It is the result of lack of resolution or of the nature of image processing in the nerves of the retina and brain. David R. Ingham 20:15, 19 May 2019 (UTC)
