Document Summary
The perception of colour is based on the way an object and surfaces we look at, reflect wavelengths. Colour perception is a subjective experience relating to how the different wavelengths of light affect certain cones in our retina. These reflected wavelengths trigger specific patterns of response in our brains that give us our experience of colour. Colour adds to the richness of our visual experience. With colour you will have an easier time picking fruit and birds out in nature, and separating the foreground from the background. Many birds, fish, reptiles and insects have excellent colour vision. With mammals colour vision is limited to primates (dogs cats and bulls do not have colour vision). Primates have 3 types of cone in the eye that are used for colour vision. Added contrast between objects and their background. Especially used for distinguishing red and yellow against a green background (making it easier to forage for fruit in bushes)
