Subjects were asked to identify colors in the Munsell notation, without comparing with the samples of the Munsell Book of Color , and then were immediately told the values of H, V , and C. This training was carried out with 520 colors identified twice by each of five subjects, two experienced and three completely naive with the Munsell system. The effect of training was noticeable over the series of 1040 estimations, and the means of absolute deviations at the end were 3.1, 0.5, and 1.25 for H, V , and C , respectively. Systematic shifts of mean estimations from the Munsell notations were noted: saturated colors tend to be judged lighter when V < 5, there is a tendency to scale compression in the estimation of C , and colors of hue between 7.5B and 7.5B tend to shift toward B, and colors of 10PB and 2.5P, toward P.
