Sir Thomas Young proposed the theory of trichromatic vision, stating that the human eye has only three types of colour receptor cones that are sensitive to red, green, and blue light. He explained that all other colours are perceived as a result of additive or subtractive combinations of these three primary colours. This theory has been widely accepted and is the basis of modern colour vision research.
