well, rgb is 16777216 colors. Lets say not all of those are acceptable skin tones, but there's a broad spectrum that's allow. for the sake of argument, lets go with a million. Not to be crazy racist, black white brown red and yellow are all adjectives used to describe skin color. skin color is a big slice of the color spectrum.
so, out of a million colors pick 8. what are the odds i pick the same 8? (if you don't remember combinatorics, a million choose 8 is on the order of 10^40).
Even if you dispute the full million colors are available, restricting our choice to just 100 unique skin colors, choosing 8 is over a hundred trillion combinations.
I'd say the odds of you and i picking the same 8 colors are pretty darn small.
