A secondary rainbow, at a greater angle than the primary rainbow, is often visible. The term double rainbow is used when both the primary and secondary rainbows are visible. In theory, all rainbows are double rainbows, but since the secondary bow is always fainter than the primary, it may be too weak to spot in practice.
A moonbow (also known as a moon rainbow or lunar rainbow) is a rainbow produced by moonlight rather than direct sunlight. Other than the difference in the light source, its formation is the same as for a solar rainbow: It is caused by the refraction of light in many water droplets, such as a rain shower or a waterfall, and is always positioned ...
In secondary rainbows, that order is reversed with violet coming first from top to bottom. A secondary rainbow is much fainter than a primary one because the intensity of light is reduced.
Rainbows. These result from a combination of internal reflection and dispersive refraction of light in raindrops. Because rainbows are seen on the opposite side of the sky from the Sun, rainbows are more visible the closer the Sun is to the horizon. For example, if the Sun is overhead, any possible rainbow appears near an observer's feet ...

Alexander's band lies between the two rainbows. Dark area between rainbows known as Alexander’s band, with a rare twinned primary A diagram of the phenomenon known as Alexander's band, a dark band that appears between any set of two rainbows which is the result of differing angles of reflection of light through water droplets.
