makeup for dark brown hair
Not all olive skin tones are cool - some are warm-neutral. I'm in this category being NC 25, so not dark though. I do agree with the bronzer instead of blush. Higher-contrast between skin and hair can usually go with some bolder makeup looks in general. Smoky-type of eyes can look fabulous, done in neutral tones, or leaning a bit cool for more drama. Rich lip colors like wines, deeper mauves, browned reds can all look wonderful.
