Color processing in the brain is a complex process that occurs in multiple stages:

  • Light enters the eye and stimulates cone cells in the retina
  • Cone cells convert light into electrical signals
  • Signals travel through the optic nerve to the visual cortex
  • The brain processes these signals in the V4 region of the visual cortex

The brain doesn’t just process individual colors; it considers context, lighting, and surrounding colors to create our final color perception. This is why optical illusions can trick our color perception and why we can recognize colors under different lighting conditions (color constancy). The brain also associates colors with emotions and memories, influencing our psychological response to different hues.
