Color exists on a continuous spectrum, but we bin them with names and descriptions that reflect perception and sometimes culture. We saw this with gender a while back. Wikipedia has a short description on culture differences and color naming.
Muyueh Lee looked at this binning through the lens of English versus Chinese color naming. More specifically, he looked at Chinese color names on Wikipedia and compared them against English color names. This comes with its own sampling biases because of higher Wikipedia usage for English speakers, but when you divide by color categories, it's a different story.
