Document Summary
Colour perception is based on the existence of three types of cones supporting evidence: any colour from mixing three wavelengths o trichromats, dichromats, monochromats.

Opponent process theory of colour cells in the visual system respond to red-green and blue-yellow colours: hering (1878) supporting evidence some colours cannot exist together, whereas others can negative afterimages.
