May 29th - Roy G. Biv

This is a re-shoot of the white rainbow shot from day before yesterday. This time, I shot during the day in full sunlight and it's a bit more colorful. I shot this on white paper in the back yard in direct sunlight, but I put a box out camera-right to cast a shadow to give the rainbow some contrast. White paper in direct sun was too bright.
