In a word, NO. Dark brown add black hair make a beautiful contrast with light skin.
Wynona Ryder’s non-descript light brown hair looks wimpy by comparison. Nevertheless, I’m sure she would look even better with cool makeup. Her foundation, blusher and lipstick are in the orange family – a color that makes black appear a little more harsh than with pinks tones (as seen in the photo left). Most makeup artists assume people with olive skin have warm skin. Not so.
Incidentally, African Americans fare better lightening their dark brown locks than do Caucasians.
