By observing 262 infants ranging in age from 69 days to 24 months the experimenter found that subjects begin to perceive colors, at least to a certain degree, at the age of three months. The criterion of perception of color was the grasping or reaching reflex. Individual differences in color discrimination are most marked between the ages of six and twelve months. Girls are more responsive to color than boys. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
