COMPLEMENTARISM

Physical and PsychicalMany efforts have been made by physicists to account for the facts, the most generally accepted theory being the Young Helmholtz theory, hich starts from the existence of three primary colour-qnnlitiey - red. Green, and violet. It is argued that since the mixture of these in right proportions gives all the colour-qualities at a relatively great degree of saturation, there fore there are three elementary stimulations and three primary sensations corresponding to them. These stimulations are made possible by the functions (according to Young) of three kinds of nerve-fibrils, or (according to Helmholtz) of three chemical substances. The sensation of red is the result of the stimulation of one, the sensation of green the result of another, and violet of a third. Now. Light excites all three of these nerve-fibrils or substances, but with different intensity. According to the wave length. Every colour-sensation, then, peripherally excited, means a certain l mixture of these three elementary stimula tions.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
