Abstract
Abstract Investigation of human colour vision relies primarily upon psycho-physical methods which require active observer participation in the experiments. The principal results of such experiments are stated and discussed in relation to the functional organisation of human colour vision. Generally, objective techniques, such as electro-physiology, are employed in the study of colour vision responses in non-human vertebrate species. The structural and functional organisation of vertebrate colour vision as revealed by these objective methods is described and the relationship between objective and psycho-physical results examined. Other sections of the article are concerned with defective colour vision and with parametric variations in normal colour vision. It is concluded that a reasonably consistent scheme for the organization of human colour vision emerges from the various types of experimental investigation, and that this scheme is adequate for the interpretation of a variety of colour vision phenomena.
