| Research Abstract |
Dichromatic simulations are used widely in social and educational environments. We used a visual search task to investigate the validity of the dichromatic simulation proposed by Brettel et al. The stimuli consisted of 13 colored disks (one target and 12 distractors). Two colors were assigned to 6 disks as distractor colors. The reaction time required to find the target was measured. The reaction times for trichromatic observers in the dichromatic simulated color stimulus task were qualitatively similar to those obtained from extremely deuteranomalous observers in an original color stimulus task. However, the reaction time for the extremely deuteranomalous observers tended to be longer than that of the trichromatic observers. This suggests that the current dichromatic simulation should be modified for estimating color differences in the simulated images.
