As I prepared to take a sunset photo near the town of Peel on the Isle of Man, I was amazed by this reddened rainbow. If the Sun has just set, as was the case on this spring day, rainbows are in essence red bows. The violet, blue, green, and yellow colors are extinguished by the greater path-length of sunlight when it traverses the atmosphere near the horizon as opposed to approaching from directly overhead. Rainbows arch high in the sky when the Sun is just setting or rising. Note also the dim secondary bow. Photo taken on April 29, 2008.
