Abstract. Purpose:To report changes in color confusion in congenitally color deficient persons following aggravation of environmental factors. Cases and Method:This study was made on 343 persons. The series comprised 51 protanopes,116 deuteranopes,51 protanomalies,82 deuteranomalies,and 43 persons with normal color vision. Their age ranged from 15 to 39 years. They were asked to name the color of square samples of 30 mm×30 mm in size(A)and circle samples of 5 mm in diameter(B). The samples had 12 kinds of hue of middle chroma and low luminosity. Results:The rate of false answer was higher for samples B than A of every type of color vision. The rate of false answer for samples B of anomalous trichromats was nearly equal to that for samples A of dichromats. Conclusion:Rate of false answer increased significantly flow low-luminosity samples by dichromats and anomalous trichromats. Rate of false color recognition increased even in anomalous trichromats in aggravated conditions.
