Pigment Powder as cosmetics

Using pigment powder, that is also used to color soaps and other cosmetics, to color my lip gloss, so that way it matches my eye shadow, which is also the pigment powder, as it is multi-use.  Any pigment powder or eye shadow can be used to change colors, just make sure that you do not lick it a lot or swallow it, as it may not be good if ingested internally.
