Forty chromatic colors, R, YR, Y, GY, G, BG, B, PB, P, and RP hues of various tones were rated by three different groups of female college students (N=46, 50, and 87) in different years on five Osgood-type Semantic Differential 7-point scales. The group averages of ratings on each scale for these single colors in the first two groups were analyzed separately using multiple regression formulae. High partial regression coefficients of determination (0.70–0.87) were obtained in both groups. These two results were analyzed on two orthogonal scales, the 5R-5BG metrical and Y–PB non-metrical scales, according to the opponent color theory. The analysis indicated that colors were felt to be more sporty and more favorable as the Munsell Hues approached BG on the former scale, and more noisy and more favorable in the P–B side than the Y–G side on the latter scale. The validity of the obtained formula was supported by the results of the third group.
