It has been reported that the constant hue locus of unique red for colored light plotted on the CIE (x, y)-chromaticity diagram is quite different from the constant hue loci of the Munsell 5R and NCS R not only its location but also the direction of the curvature. No study has been done to investigate whether this inconsistency in the red region is due to the difference of color media the difference of stimulus mode, the difference of an experimental procedure, or the individual difference among observers. Thus we measured the hue of color stimuli presented in a surface-color mode (color charts and CRT color stimuli with gray surround) and in a self-luminous mode (CRT color stimuli with dark surround) using two kinds of color naming technique, an opponent type, and a categorical type. The results of six observers showed that the unique red locus in color chart is located near the constant hue loci of the Munsell 5R and NCS R while the location and the curve shape of the unique red locis in the CRT dark-surround is different from it. It is suggested that the mode of appearance is the most effective cause for displacement and distortion of the unique red locus on the chromaticity diagram.
