Instituut voor Zintuigfysiologie TNO Publication year 1974 Abstract On the basis of new experimental data of tritanopic vision the convergence centre for tritanopia has been redetermined, and has turned out to bex' = 0.1747,y' = 0.0060 in the Judd 1951-chromaticity diagram. A consequence of this determination is that the blue system is more sensitive than was concluded from the Thomson-Wright (1953) study. The spectral sensitivities of the three colour mediating systems are derived. The ratio of the number of “red”, “green” and “blue” receptors in normal trichromatic eyes is derived to be 32:16:1.
