Comparison of chromatic‐adaptation transforms

Abstract Eight methods of chromatic‐adaptation transformation have been compared as part of a CIE activity. Variability among the methods is about ten times as great as that for color matching in terms of radii of ellipses. There appear to be two general classes of prediction. One class agrees in whole or in part with the von Kries coefficient rule. The other does not. CIE TC 1.3 Subcommittee 2 on Chromatic Adaptation, is anxious to determine which of the two classes of prediction best represents practical observations of the influence of chromatic adaptation on color appearances.
