Two color‐memory experiments were performed to investigate whether observers tended to confuse colors with a smaller color difference in memory or colors in a same color‐category region. We made color stimuli on a color CRT. 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 difference can be confused more easily when they are in a same color category than in different color categories, and that colors identified with memory tend to distribute within their own color‐category regions or their neighbor color‐category regions, depending on their positions in a color space. These findings indicate that color memory is characterized by the color categories, suggesting a color‐category mechanism in a higher level of color vision. © 1996 John Wiley & Sons, Inc.
