I think that's an interesting quiz. It's deceptively simple (but I couldn't get all of them). Did you know, some people did some research in the 1960s (Berlin and Kay) about words for colours in different languages. Some have lots, some have a few (eg only 3 basic ones). But the theory is, those with 3 are always the same 3, and if different languages have 6 they're always the same 6. Interesting stuff...
