Hidden color

We have had a lot of rain this summer, but not many rainbows. Actually, this is the first I have seen this year. And it was spectacular... photos do not really do them justice.

It is amazing to me that drops of water can break light into its chromatic components. Rain acting as a lens or prism revealing color from where there is apparently none. But that should not be a surprise because white light is actually light of all colors mixed together. Maybe there is a thought there... do not look only for the homogeneous whole, look for the color hiding inside.
