Flowers for the bridemaids?

i think that if you were to do brighter flowers, it would be too busy, but if you were to do one uniform color, one that would go with all the dresses, it would look ok. i'm all for bright colors, but you also don't want it to look like it's all been thrown together. maybe one color of a bright flower, and then the same color of another flower in a more pastel shade. if you did that, like having yellow flowers for the girl with the yellow dress, etc., and then use a bright ribbo in the same color, it would look good. that way it'd still be bright and cheery, but not all over the place.
