James Clerck Maxwell
It is difficult to explain to the outside observer just how famous Maxwell is amongst physicists. In addition to his «Theory of Colour Vision», which is seen as the origin of colorimetry, his name is linked to the four so-called field equations which are able to explain how light propagates, and thus point to the existence of electromagnetic waves. We make use of the reception of these waves today, for example when we listen to the radio. After discovering equations which could record colours, Maxwell placed the resultant combinations in a
Date: James Clerck Maxwell, the physicist, presented his theory of colour mixing between 1855 and 1860.
Country of origin: England
Basic colours: Red, green and blue
Application: The system is a fundamental requirement for colorimetry.
