2 December 2011
The lecture, given by given by Professor Mohamed Sobhy, of the University of Kent in the Gulbenkian Theatre Canterbury on 30 November, contained a wonderful galaxy of colour demonstrations.
Professor Sobhy pointed out that these were the result of the interaction of physiology, psychology and the environment.
The trichromatic and the opponent therories were demonstrated which involve, respectively, the addition and subtraction of colours.
He generated colours witout pigments plus interference and birefringence colours. 3-D colour pictures were projected which were examined using red and green glasses by all.
Prof. Sobhy also provided notes for obtaining the materials used and appropriate web sites for information, purchases, and instructions.
