  • Abstract
  • Look Inside

The author devised the Saturation Discrimina-tion Test (SDT) composed of 93 colour caps chosen along the tritanopic confusion line including Illu-minant C on the CIE chromaticity diagram, to determine the saturation descrimination ability of subjects with congenital and acquired colour vision deficiencies. All colour caps were of the same Mun-sell Value 6 brightness and the colour difference was even (ΔE= 1) between each cap, as defined by the equation CIE 1976 L*a*b*.

120 normal colour vision subjects, 50 cases of con-genital colour vision deficiencies and 31 cases of acquired colour vision deficiencies were tested by the SDT.
