What color mascara should I use?

I honestly wouldn't notice any difference. I have dark brown hair, very pale skin and slightly greenish brown eyes with eyeliner, and I use black, but I spent ages wearing black/brown because my mum thought it was less harsh, I never saw any difference. If it's black eyeliner it would make sense to use black mascara, though if the eyeliner is brown or any other colour, I'd use black/brown :) It's up to you really and I don't think it makes a big difference

Brown for everyday and black for a more dramatic look :)

black it makes your eyelashes look longer and thicker in my opinion and no offense to any people who do wear brown mascara but i think brown looks really bad on most people

Black, I find brown is just awkward lol. It also makes your lashes thicker, in my opinion

Dark brown...it's dramatic but not overly so.
