[Study on color misnaming among the congenital color vision anomalous--Part 2. Lightness and saturation of color misnomers].
I analysed the misnamed colors reported previously by plotting them on the value and chroma diagram. The study included at least 3 subjects for protanopia and at least 5 subjects for deutanopia on the same misnomer applied to one test color. The test colors were expressed by the Munsell color notation system. Deutanopia: High lightness value group (value 5 or more); Gr and lightly saturated G-->pink (test color-->misnomer), intermediately saturated YR and Y-->yellowish green, GY-->skin color, highly saturated GY-->orange, RP-->grey in wide range, lightly or intermediately saturated BG-->grey in many cases. Low lightness value group (value 4 or less); Gr-->green, lightly saturated Br-->green, intermediately saturated YR, GY, G and RP-->red, highly saturated R-->brown, YR-->green, intermediately saturated BG and B-->purple, intermediately saturated PB and P-->blue. Protanopia: RP-->red, PB-->purple, P-->pink, low lightness value lightly saturated BG-->black (this pattern was different from deutanopia), GY-->skin color (this pattern was shifted to the lightly saturated area), YR, Y-->green (more frequent in protanopia). YR, Y-->yellowgreen (more frequent in deutanopia). On the warm color side low sensitivity was anticipated not only for R but also for YR, Y, and GY. This anticipation will be substantiated by increasing the test subjects.
