Characteristics of dichromacy showing wavelengths nm of neutral points and confusion points for indicated illuminant CCT, hue names of confused hues, and of residual hues.

All name pairs are complementary. Means are weighted by number of observers and exclude Judd [25] and Wyszecki & Stiles [2] unsourced estimates. Mean* (under “Deutan”) denotes mean without suspect Hecht data. “Obs” denotes number of observers. Wavelengths in parentheses (including means) represent adjustment to align with illuminant CCT 6600K. Judd's neutral points are from his Fig. 2.14 (confusion loci) not Table 1.3 [24]. Under References only the 1st author is listed. CCT means illuminant Correlated Color Temperature, degrees Kelvin; “dark” means dark adapted. Note Walls specified his Illum C as 6500K.Characteristics of dichromacy showing wavelengths nm of neutral points and confusion points for indicated illuminant CCT, hue names of confused hues, and of residual hues.
