Concentrations of Yellow and Purple

My friend needed a centerpiece for her kitchen table.  Yellow and purple were the colors of the day. One balances the other.  Soldago (yellow feathery flower) with yellow mums counters the ornamental cabbage, purple mums and limonium (feathery purple flower).  Proteus mounts the top predominantly red but picking up the purple in the mums.  The arrangement is balanced by a big sunflower on the other side.
