I wonder why nature likes to pair certain colors... As I took this picture that thought occurred to me. Eggs come to mind but there is an extensive list of flowers in these paired colors; daffodils, daisies, roses, water lilies, day lilies, cala lilies, chrysanthemums, plumeria, and dahlias to name a few. I suspect it has something to do with the way insects perceive color and pollination. Regardless of the reason the contrast is quite attractive.
