What sort of cosmetics would you use to apply make up to these hypothetical Indians, of troy?
Rouge, I suppose, wouldn't be much good, although scarlet nail varnish might look good on the Blackfeet.
It'd be no good giving them powder unless you gave them shot as well.

Mind you, back in the 50s, my sister-in-law used to refer to their cosmetics as "War Paint," so I s'pose the whole thing ain't so silly.
