Abstract. Purpose:To report the frequency of color confusion in objects by congenital color-deficient persons. Method:This study was made on 492 persons with ages ranging from 16 to 38 years. The series comprised 70 protanopes,158 deuteranopes,70 protanomalies,141 deuteranomalies,and 43 persons with normal color vision. They were asked to name the color of blue-green,red-purple or gray cards presented to them. Results:Protanopes and deuteranopes showed a high incidence to name blue-green or red-purple as achromatic and to name achromatic as chromatic. The incidence was higher in dichromats than anomalous trichomats. Conclusion:Persons with congenital color deficiency may name achromatic cards as chromatic ones. This fact is important in understanding color confusion by color-deficient persons in their daily life.
