The current understanding of color vision is that it begins with a trichromatic process in the cones of the retina, which detect red, green, and blue light wavelengths. The information is then processed in the visual pathways and eventually converted to an opponent process when it reaches certain cells in the retina and brain that respond to pairs of colors (red/green, blue/yellow, black/white) in an antagonistic way. Therefore, color vision begins as a trichromatic process in the retina and later switches to an opponent process.
