On any budget a monochromatic color scheme can pull a room together, adding up to a result that depends less on individual elements than on the overall look. Few will notice, for instance, if the pink flowers are carnations and chrysanthemums instead of more expensive roses or peonies, as long as the other similarly hued details work well together. "Using a beautiful pale pink tablecloth, napkins and flowers can look more powerful and substantial than having several colors," says N.Y.C. planner Jennifer Brisman.
