Evolving in a silent, dark world, organisms developed receptors that could detect and differentiate components of the electromagnetic spectrum from the sun. Computation of the proportions of different wavelengths emitted from objects is used to form the perception of colour by the visual system, enhancing the ability to differentiate objects from background. The beauty of colour, used by individuals, artists and commerce is important in all cultures from pre-history to the present.
