Names for colors arose relatively late in human history and tend to be unique to each culture and are usually not loan words, the only exception being orange, which tended just about everywhere to be named for the fruit of that color, which is interesting, it’s probably the last of the colors identified in common human speech.
Meanwhile, color perception and psychology varies from culture to culture. So e.g. black is the color of mourning in the english speaking world because it reflect austerity, somber sadness, whereas white is the color of mourning in China, because the soul is purified of its’ wordly sins at death to be wiped clean and readied for the next incarnation.

“Yellow” in Chinese means anything from light green to dark brown. 黄 is the image of a straw leather stuffed target OR the image of a person bearing a yellow jade pendant.
