Abstract:In this paper, a model to teach colour vision is presented. Three different types of the cones that enable colour vision are visualized as bottles, and the amount the different bottles are filled is associated with the appearance of colour that is formed by the brain. It is shown that the appearance of colour depends both on the relative and the absolute filling of the bottles. We focus on the spectral composition of light reflected from brown surfaces and show that when we see brown, there is usually red, yellow, orange and green light falling into our eyes, but of low intensity. The same spectral composition of the incident light would give the impression of orange colour if the intensity of light were higher.
