Description

The purpose of the present study consists of the following two items: (1) to clarify the cause of the significant difference found between the total variation and the estimated change due to age differenceof color matches on metameric-sample pairs for color-normal observers from age 20 to 60 studied by P. K. Kaiser et al (Color Res. and Appl. 5 (1980) 65), and (2) to confirm whether the metameric-sample pairs of the Davidson and Hemmendinger (abbreviated by D · H) color. rule are representative for assessing the relation between observer and illuminant metamerism index. The former is analyzed by using the D · H color-rule samples and the Stiles's 20 color-matching functions. The latter is studied by using the Wyszecki's 12 gray metameric-sample pairs.<BR>Results are summarized as follows: (1) The significant difference between the total variation and the age effect found in the study by P. K. Kaiser et al. is supposed to be caused mainly by the matching errors of their observers in this kind of experiments.(2) The D · H color-rule samples can not be representative for determining the relation between observer and illuminant metamerism index.(3) The Stiles's 20 color-matching functions are suitable for assessing observer metamerism on color-normal observers.
