title: Relations between inter- and intra-individual variability of color-matching functions. Experimental results.
abstract: Color-matching functions, as well as the variances and inter- and intra-individual correlations, are given for ten subjects. The dispersion found in the blue region is greater than that indicated by Stiles and Burch. The color-matching technique used is thought to be the cause. Consequences of intra-individual variability are evaluated. A comparison is made with scores of subjects on the Davidson and Hemmendinger color rule. The chromaticity diagram is shown to give an unsatisfactory representation of individual variations.
