The present paper describes a general method to derive spectral power distributions of the illuminants, which have a general color index of 100 with respect to any reference illuminant.
Some of these test illuminants are shown, as example, with respect to the CIE standard illuminant C, and these spectral power distributions are constructed in order to have relatively large deviations from those of the illuminant C in spite of the general color rendering index of 100.
These derived distributions for test illuminants were applied to 12 gray samples, which were in metameric match, respectively, under the CIE standard illuminant C and the CIE 1931 standard observer derived by G. Wyszecki.
However, it was confirmed that the discrepancies of chromaticity coordinates of those 12 gray samples were relatively small under the test illuminants in spite of large inconformity of spectral power distributions with the standard illuminant C.
