A team of researchers with members from the University of Sussex and the University of California has found evidence that suggests color categorization in humans is biological rather than learned. In their paper published in Proceedings of the National Academy of Sciences, the group outlines the experiments they conducted with infants, what they found, and what they believe their results suggest about the nature of color differentiation in humans.

Non-colorblind people take color vision for granted—it is part of automatic processing. They see something and place it into a color category: red, green, blue, orange, etc. But scientists have not been able to agree on whether such categorizing is the result of behaviors learned from others or if it is at least in part hardwired. To learn more about color categorization, the researchers with this new effort studied babies, hoping to figure out if they categorize colors in ways similar to adults before they learn the words used to describe them.
