Have you ever seen a white rainbow? Probably no, as such fogbows are extremely rare phenomena.

Melvin Nicholson was lucky to be there at the right spot to capture this stunning photo of the rare apparition on Rannoch Moor on November 21, 2016.

A fog bow is a similar phenomenon to a rainbow, but in fog rather than during rain. Because of the very small size of water droplets that cause fog, the fog bow has only very weak colors, with a red outer edge and bluish inner edge.

When the droplets are very small, fog bows appear white – like on the above picture – and are therefore sometimes called white rainbows. The fogbow’s lack of colors is caused by the smaller water drops … so small that the wavelength of light becomes important.

Just beyond magical: the fog bow, a wonderful isolated windswept tree, and freshly fallen snow around.
