If blackface is so offensive to black people, then why do some of them wear inappropriate shades of lipstick?

There's a black girl in my class. I have nothing against her other than the fact that the way she did her make up today resembles blackface. She is involved in the fashion industry and should know how to select a shade of lipstick. Instead of choosing a sexy burgundy, she chose neon pink. I doubt society would tolerate a white person choosing black foundation.

Every day white people like me are reminded of our cultural guilt and dept to society. I don't think that she should rub this in my face by actually imitating the exact image that she claims that my ancestors wrongly projected onto her. Should I tell her how offended I am?
