Groomsmen colors-vests&ties

I have a question - My BM dresses are green with pink sashes (pic in album) I want my FH to have a white shirt, white vest & white tie.... For the groomsmen I don't want pink or green or anything like that. Is it normal and ok for the groomsmen to have black? (black tux, black vest & black tie --- white shirt)???
What is everyone having?

Thanks!

By the way - I was thinking about having silver/grayish ....... but.... I think the girls are going to have golden accesories (shoes/bag/jewelery b/c it goes really nice with the dress) so I don't want to mix too much....

HELP!

Oh geez Gabbie...I have no idea...My girls are in green too and my dress is diamond white with champagne accents...no clue what I'm doing either...sorry...no help here...just letting you know that I feel your pain...

ok well i feel better :)
