The Difference of Categorical Color Perception between Young Adults, Elderly People and Color Deficiencies
We carried out a categorical color naming experiment using young adults, elderly people and color deficiencies as observers. The experiment was designed to investigate the effects of illuminant (four types of fluorescent: D-EDL-D65, N-EDL, EX-L and W) and illuminance (three levels: 10, 100, 10001x). The experiment used a series of Munsell chips which were presented separately, and the observers were asked to categorize them into one of 11 categories (red, pink, orange, yellow, green, blue, purple, brown, white, gray, and black). The consensus of the categorization results was relative high for the young adults but not for the elderly observers and severely color deficiencies. The elderly observers categorization consensus was low for chips with hues RP, R, YR, and Y. It also much deteriorated when either the illuminance was low, or the lightness of the chips was either low or high in the elderly group. The categorization of severely color deficiencies were quite different from the young adults regardless of the illuminant or illuminance.
