Categorical color naming of surface color codes by people with abnormal color vision

Abstract

PURPOSE. Past investigations of the ability of people with color vision deficiency (CVD) to name the colors of surface colors have been occupation-specific. This study was undertaken as a more generalized investigation to explore particularly the effects of stimulus size and shape. METHODS. One hundred CVD observers and 20 color vision normal (CVN) subjects named the colors of two sets of surface colors, each set presenting the same 10 colors (red, orange, brown, yellow, green, blue, purple, white, gray, black). One set presented dot stimuli in three sizes (2.4°, 1.0°, 0.27°) and the other line stimuli with three widths (0.50°, 0.27°, 0.14°). Color vision was diagnosed using the Ishihara tes..
