CAMP VERDE, Ariz. - This picture of a rare fogbow was taken by Brylee Dugan in Camp Verde Tuesday. That’s right, I said “fogbow.”

If you’ve never heard of a white rainbow or a fogbow, you’re not alone.

Fogbows resemble normal rainbows without the color. They appear in fog that is thin enough for sunlight to shine through.

The main difference between a fogbow and a rainbow is the size of the water drops involved.

The reason fogbows appear white is because the water droplets reflecting the sunlight are so small that they smear out the colors, according to NASA.

Fogbows are sometimes seen with a tinge of red on the outside and blue on the inside, according to the National Weather Service.

As with normal rainbows, the best way to see a fogbow is with the sun behind you.
