It's more charitable to assume that this would be a set of six+ colors from pale to deep. You're making unwarranted assumptions.
To respond to your point below, all major manufacturers now make a range of "nude" colors. The range of colors may be stunted, on both ends, but if you've shopped recently you know that a range is easily available.
There isn’t in practice so you are soeaking naively for no good reason. A company that wanted to shed the term would say something like “seven skin tones” if they offered more than one “nude”
Skin color comes from just three pigments: eumelanin, pheomelanin, and hemoglobin. There are more pigments than that in the paint mixer at the hardware store.
It probably would not be extremely difficult to come up with a way to automatically generate a custom dye mixture that exactly matches a given skin color, out of just blacks, browns, and reds.
> Who’s “nude”? When is the industry going to update this term?
Reminds me of a scene from some sitcom I can't remember, where a guy is trying to be inclusive, so he says "We employ people of every race here- black, yellow, brown, and normal."
