Is Color Vision Deficiency a Handicap to Coloring?

Abstract

Is color vision deficiency a handicap to coloring? To approach this question, we experimentally examined colors used by individuals with color vision deficiency in coloring tasks. We converted 25 referring object images to line drawing images, and created the experimental program for coloring tasks. Participants colored each area of the line drawing stimuli to obtain the same color while referring to the image. The results revealed that the participants with color vision deficiency selected colors similar to those of normal vision for more images than expected, whereas they used different colors for images with long wavelength colors or low saturation.
