But did you know that there is also such a thing as a night rainbow???? reddit.com It's called a lunar rainbow, or, cutely, a moonbow. Moonbows are formed the same way as day rainbows, by refraction of light in water droplets. commons.wikimedia.org However, with a moonbow, that light comes from — you guessed it — the moon, not the sun.

If you're trying to spot a more distinct moonbow IRL, here are a few tips: 1. They're most often visible during a full moon, when light is bright enough to empower refraction. Flickr: 8987884@N07 2. Moonbows often appear white to the naked eye, because moonlight is dimmer than sunlight and doesn't trigger your eyes' color receptors with the same intensity.

"Spray moonbows" are pretty reliably seen near waterfalls, which fill the air with water droplets.

Happy moonbow hunting!
