Paper Abstract

Categorical color naming experiment was carried out in the entire visual field using five test stimuli, R, Y1, Y2, G, and B which appear red, dark yellow, bright yellow, green, and blue, respectively, at the center of the visual field. The observer reported color appearance of the test stimuli using only one of 13 color terms (11 basic categorical color terms, yellowish-green, and aqua-blue). The test stimuli were presented at 0 deg and from 10 to 80 deg in the eccentricity with 10 deg step for each of the 8 directions. The constant color name region where the same color name as used at 0 deg was obtained was clearly larger for Y2 and B than those for R and G, while that of Y1 was in between. Approximate size of the constant color name region of monocular viewing extended 30 deg in the nasal and upper, 40 deg in the lower, 70 deg in the temporal visual fields. Outside of the region, the categorical color responses became unstable and in the far periphery achromatic color names such as white or gray often appeared in all of the test stimuli.
