1958 W. A. H. Rushton in Nature 13 Sept. 691/1 This latter pigment may be named ‘erythrolabe’ (= red taking), the protanope pigment ‘chlorolabe’, [etc.].
1959 Optica Acta 6 171 As the interaction between perceptual and physical processes is not likely to take place at a receptoral level, the terms chlorolabe and erythrolabe..are here replaced by C.P.540 and C.P.600.
1963 Jrnl. Physiol. 168 358 The ‘green pigment’ of colour vision is not that which would look green if we could extract it, for in that case green rays would be transmitted unabsorbed and without effect. Quite the contrary, it is the pigment which catches green—chlorolabe.
1975 Sci. Amer. Mar. 71/3 D. E. Mitchell and I applied the same test to see whether or not the cone pigments chlorolabe or erythrolabe in the dichromat are the pigments of daylight vision in the protanope or the deuteranope.
