Yellow
Per a basic dictionary definition, yellow is a component of light, the most luminous of the primary colors, occurring in the spectrum between green and orange, with a wavelength between 570 and 590 nanometers. Part of growing up in the United States is to eventually begin associating a handful of basic colors with racial categories and, along with them, prescriptive notions of race. Together with the cognate colors white, black, red, and brown, yellow has come to signify a major racial category in the United States.
