Double Rainbow, Albion Basin, Little Cottonwood Canyon, Utah The rainbow we normally see is called the primary rainbow and is produced by one internal reflection; the secondary rainbow arises from two internal reflections. If you look at the order of the colors you will see the secondary rainbow's colors are the reverse order of the primary.
