Abstract
AbstractMany kinds of research have been undertaken on color constancy under various illuminations; however, not many people have studied this domain in the context of vivid colored light. In this article, 23 color chips were assessed using the elementary color‐naming method under 13 RGB‐LED illuminations of six hues as red, yellow, green, cyan, blue, and magenta. A total of 100 subjects participated in the study and reported that color chips of cyan, yellow, and green light were not good as compared to the others. This article also proposes an elementary color‐naming method as an alternative way to study and calculate color constancy index using the two rooms technique as extending experiment booth to get the color appearance of the color chip without adapting to the colored illumination. Our results suggested individual color appearance performance for each colored light which yellow, cyan, and green are not recommended as shown by poor area ratio and color constancy index.
