The order in which colors are named worldwide appears to be due to how eyes work. Researchers have found that colors familiar to one culture might not even have names in another, suggesting that different cultures indeed have different ways of seeing–and understanding–the world.
Color names always seem to appear in a specific order of importance across cultures: black, white, red, green, yellow and blue. In LiveScience, Charles Choi quotes physicist Francesca Tria as saying, "If a population has a name for red, it also has a name for black and for white–or, if it has a name for green, it also has a name for red." But if a population has a name for black and white, that doesn’t necessarily mean they have a name for red.
