Abstract

Boynton & Kambe (Boynton and Kambe 1980) measured chromatic discrimination along critical axes in color space. These axes were lines of constant L/L+M excitation and lines of constant S-cone excitation, which are respectively vertical and horizontal lines in the MacLeod- Boynton (MacLeod and Boynton 1979) chromaticity space. Discrimination along constant L/L+M lines depended on S-cone excitation and showed no effect of L/L+M excitation. Discrimination along constant S-cone excitation lines showed a minimum near the L/L+M chromaticity of 570nm and additionally showed a small effect of the level of SWS cone excitation.
