It got dark in the early afternoon as a line of thunderstorms rolled in. A couple of hours of heavy rain helped cool the house down. I was sitting down processing some images and all of sudden it started getting bright outside. As I looked out the clouds were getting lit by the setting sun. Then I saw a rainbow appear. By the time I got outside with a camera the color of the sky was changing, first to orange, then to pink. I got a few shots before the rainbow disappeared.
