At the level of the cones, color vision occurs via a trichromatic process (three types of cones respond to different wavelengths of light). However, along the neural pathway from the LGN to the visual cortex, the process is an opponent one (opposing pairs of colors are processed in the visual system). This is known as the opponent-process theory of color vision.
