Note on color preference and color vision test performance

The incidence of color deficient vision was investigated using the Pseudo-Isochromatic Plates on a relatively large and representative group. In the sample of 112 adults aged 20 to 80 yr. and comprised of 53% women and 12% minorities, 8% of men and 3% of women were color deficient. Over-all performance indicated no effects for sex or race. Nearly half of the plates were nondiscriminating among sex, minority/majority, and "normal" and "defective" color vision groups. Named color preferences within the "normal" group strongly favored blues and reflected no sex differences.
