Abstract

Presently there are two dominant theories for human color vision: Young-Helmholtz-Maxwell's Trichromatic Theory and Hering's Opponent-Color Theory. It has been widely accepted that the Trichromatic Theory holds true for retinal color processing whereas the Opponent-Color Theory works for cortical color processing-this conception has become the "Standard Model" for human color vision. My purposes in the present paper are threefold: First, to demonstrate that the Opponent-Color Theory is fundamentally untenable, based on both theoretical and empirical grounds; second, to resurrect a two-stage trichromatic model, in which both retinal and cortical color processing are trichromatic, proposed by W. McDougall more than a century ago; and third, to map the cortical color processing stage (which directly correlates with color consciousness) in this model to layer 4 within the primary visual cortex (V1) of the human brain.
