Colour constancy

  • Colour constancy is the ability to perceive colours as relatively constant, even under changing lighting conditions.
  • Colour constancy refers to the perceptual ability to compensate when changes in illumination would otherwise cause things to appear to be change colour.
  • Colour constancy is an extreme case of chromatic adaptation that associates a particular colour with an object regardless of changes in lighting.
  • Colour vision relies on colour constancy as it allows us to perceive the colour of an object as stable, even when the intensity or spectral distribution of the illumination changes.
