Color defectives have been considered to be handicapped persons in modern-day Japan. We studied color recognition of color detectives using various clolor materials and color-blindness test. At first, a traffic signal recognition were reviewed. There were no significant differences between the color defectives and the controls. It is a distinct advantage for color detectives that the actual color of the green traffic signal light is mostly blue-green in Japan. The second and third reviews were related to the Color Mate Test (CMT) and its comparison with other color vision tests. The CMT was developed specifically to know which children will require special color consideration in classroom activities, but the Ishihara Color Charts and the Farnsworth D-15 Test (Panel D-15) continue to be used with greater frequency. CMT is the most accurate measure of color discrimination ability in daily life, followed by the Panel D-15. The Ishihara test should be considered unsuitable for evaluating color discrimination ability in daily life. When there is a need to evaluate real-life color discrimination ability, evaluations using common colored objects are the most appropriate.
