White Rainbows

Rainbows are one of the most common and beautiful things you can see. Water works as a prism to break the light into the visible spectrum of colors. But every so often, there is a special type of effect that happens when conditions are ideal.

A colorless rainbow occurs in the same fashion as other rainbows, with sunlight passing through water droplets. But in this case, it happens when fog is forming. The droplets in the fog are much smaller. As a result, most color is lost while passing through them.
