Accent Color with Begonia Bridesmaids Dresses

Hi all!

My color scheme was always going to be pink and chocolate brown. I however didn't find the shade of pink that I had in mind when we went shopping for bridesmaids dresses. We decided today to instead go with Begonia from David's bridal today which is almost a fuscia color.

My flowers can still be all different shades of pinks, but I'm not sure chocolate brown goes with the begonia. What accent color could I use instead with begonia..Maybe purples, silver????? I really couldn't have used the brown in the flowers other than maybe a ribbon around the bottom, so its not the end of the world, I just need help with a new vision!

Thanks.
