What Makes A Red Rainbow?

It's rare to see a red rainbow. A red rainbow is an optical and meteorological phenomenon and a rare variation of the more commonly seen multicolored rainbow.

Normally observed at either sunrise or sunset, a red rainbow (or monochrome rainbow) requires a particular combination of atmospheric conditions to form. These conditions are usually present at the beginning or end of the day, most often during rainstorms, fog, or mist.
