I can't for the life of me work out why that infographic is in the shape of a wheel, instead of a list with the actual meanings written next to it instead of numbers and a key.
A matrix would be much more usable indeed, but maybe the author thought colors should always be shown in 'color wheels'.
The colour wheel is interesting. Although, I wonder about "Asian" being distinct from "Japanese" and "Chinese", and I wonder why they didn't at least put these adjacent to each other, and Eastern European adjacent to Western/American.
