What are the theories of Colour constancy?

What is color constancy illusion?

How do you achieve color constancy?
Color constancy works only if the incident illumination contains a range of wavelengths. The different cone cells of the eye register different but overlapping ranges of wavelengths of the light reflected by every object in the scene.
How is color constancy achieved?
Why do we need Colour constancy?
Colour constancy is an example of subjective constancy and a feature of the human colour perception system that ensures that the perceived colour of objects remains relatively constant under varying illumination conditions.
What is color constancy and what are its limitations?

What is perceptual constancy and color constancy?
