Why are there only few colors in the rainbow?

With none of the cool colors left for the water droplets to refract, the rainbow now only features a band of red. Just like any rainbow, these rare sightings appear after rainstorms or heavy mist. The droplets lend itself for the wavelengths of light to further scatter, thus making the monochromatic effect even more obvious.

Apparently, even white monochromatic rainbows exist. After a thick fog or clouds scatters less precisely that falling rain, it can still cause an arc to form in the sky. When the colors then mix together, the arc appears as a streak of white that looks like a lit-up cloud.
