What was discovered

Opponent-process theory explains color vision by proposing that the human visual system processes cone signals antagonistically, through three opponent channels: red-green, blue-yellow and luminance.

What it led to

  • modern understanding of color perception
  • diagnosis and study of color blindness
  • design of color spaces such as CIE Lab
  • computational models of human vision
