Opponent-Process Theory

Opponent-Process Theory is a psychological and neurological model explaining how the perception of colors is controlled by two opposing systems in the brain, creating a balance between excitatory and inhibitory processes.

Cells in the retina (cones) that are sensitive to specific wavelengths of light, allowing for the perception of different colors.
