Lunar rainbow (moonbow) over the base of upper Yosemite Falls, Yosemite National Park, California, USA. The moonbow appears during spring runoff when the falls create mist and a full moon is present. Most human vision can only see the moonbow as a grayish arc as the color cone receptors are not sensitive enough to send color signals to the brain.
