Influence of Basic Color Categories on Color Memory Discriminatibn

Two color-memory experiments were perfbrmed to investigate whether observers tended to confuse colors with a smaller color diflerence in memory or colors in a same color-category region. We made color stimuli on a color CR T. Color difference was determined by a simultaneous color discrimination experiment. Color-category regions were obtained by a categorical color-naming experiment using the 11 basic color names: white, black, red, green, yellow, blue, brown, orange, purple, pink, and gray. The results show that two colors with a certain color diflerence can be confused more easily when they are in a same color category than in drflerent color categories, and that colors identijied with memory tend to distribute within their own color-category regions or their neighbor colorcategory regions, depending on their positions in a color space. Thrsejndings indicate that color memory is characterized by the color categories, suggesting a color-category mechanism in a higher level of color vision. o 1996 John M ' i k q ! & Sons. Inc.
