In the human eye, there are three types of cones which possess their own characteristic photopigments that respond to red, green and blue lights. The sensations of different colours are produced by various combinations of these cones and their photopigments. When these cones are stimulated equally, a sensation of white light is produced. The daylight (photopic) vision and colour vision are functions of cones and the twilight (scotopic) vision is the function of the rods
