A double rainbow over a tree line. The rainbow is against a dark, cloudy sky, and sunlight is beaming down on some of the trees to the left/center.
There are two rainbows—the one in the center of the image is much more vibrant than the other, which is offset to the right/above.
This photo was taken from the end of our driveway. We could see it from our house, but more of the sky is visible from the road.
