A new model for colour vision

Current models of vision cannot fully explain all aspects of colour vision. A new model for colour vision is described here that takes into consideration polarisational effects in the retina. The receptor cells can be modelled as combined half-wave plate and analyser, that in combination with the polarisational effects of Henle´s fiber layer in the macula, produces a receptor system that will respond preferentially to a particular colour to the detriment of its complementary colour. This polariser-analyser model merges colour opponency and three-colour theorems, and offers an explanation as to why yellow behaves as a quasi-primary colour.
