Bouquet colors

My dress is white, with silver beading. I'm having a bouquet of black magic roses with a few silver jewels in them. My BM's have dark platinum dresses and my JR BM has a red dress.

I was originally thinking of having Sahara rose and rice flower bouquets for all of the girls (they're sort of a creamy off white antique looking rose) , but now i'm starting to wonder if those will look ok. sort of like the picture below.

Any suggestions? I don't want pink roses for them.
Would it be weird if they had red roses also?

TIA!
