Did you know that there are often double rainbows? In a double

rainbow, light reflects twice inside the water droplets and forms

two arcs. In most double rainbows, the colours of the top arc

are opposite from the bottom arc. In other words, the order of

colours starts with violet on the top and ends with a red on

bottom. In addition, rainbows sometimes appear as white arcs

at nights. These rainbows are called moonbows and are so rare

that very few people will ever see one. Moonbows are caused

by moonlight (rather than sunlight) shining through drops of

water. by authors
