The white table cloth with the purple tulle strip down the middle. The center pieces on this table are too much. Go with a simple jar with purple glass beads in the bottom with a purple ribbon around the top and babies breath and a butterfly in each jar.
Varied glass vase and tree Centerpieces are a nice combination with the backlighting. Having the dramatic and varied colored lighting enables you to keep the tables a little more subdued with colored napkins and candles
