If my wedding colors are royal blue and silver, what color flowers would look good for the bouquets?

Wedding is May 31st, silver dresses for bridesaids, with royal blue accents, Thank you for your advice!

I know quite a few answers say yellow, but I think I would avoid yellow altogether, try to stay in the cool color palette, since your colors are cool. I think an all white bouquet will get washed out against the silver, and I think red would be bold but too bold for the color scheme.
