Theory stating that there are 3 sets of color receptors in the visual system. Stimulation of one member of a set produces the sensation of the corresponding color. Hering assumed that the retina possesses three photochemical substances that, depending on their decomposition or resynthesis, produce different colour sensations by their stimulation of different nerve endings: disassimilation producing red, yellow, and white, and restitution producing blue, green, and black.
