表色系の比較 : 花弁色に関する研究

This study was made to determine which color system (chromaticity scale) of the three typical is best to express the petal color of tulip. Fifty seven varieties of tulip were examined by each system. An analysis of the comparisons shows that :
(1) The petal color can be classified on the XYZ system.
(2) The grouping of color on the αβ system is parallel to that of the XYZ system, but not to that of the a_Lb_L system,some disorders being seen in the yellow and red groups.
(3) The αβ system and the a_Lb_L system magnify the color difference in the illuminant part on the xyz system.
