Have you ever found yourself in the paint aisle, staring wordlessly at the seemingly endless array of color fusion? I inevitably find myself staring at those swatches and wondering how on earth there can be hundreds of variations of yellow. Perhaps, I think, I’m just an unrefined savage when it comes to discerning paint color, or perhaps the colors really aren’t that different and it’s simply a trick presented by paint advertisers. However, upon closer inspection, I see the vague tinges of shade difference. So, when presented with such an array of colors and all the designating names categorizing them, I realize that we humans have a deep understanding of color variation. This ability to see color has allowed us to note the vast diversity of skin color among our own species.
