But we have many terms that are not clear cut in most western languages either.

Ask people what they consider cyan vs.turquoise, and some will insist they are the same and some will insist they are distinct. Ask them to draw a boundary between either and blue or green, and the boundaries will be different.

Ask them what is magenta vs. purple vs violet or even pink and again some will insist two or more of them are the same,and some will have strong opinions of what falls on either side that may not match the ’objective' categorization.
