A fogbow? Yes, it’s a thing.
A fogbow is just like a rainbow, but it appears in fog rather than rain, as the name suggests.
Obviously, it isn’t as colourful as its bright cousin. Rainbows are created when water droplets act like prisms, separating the white light into rainbow colours.
The water droplets which make up fog are so small (less than 0.05 mm) they can’t reflect or refract light within the drops. They’re too tiny! That’s why fogbows end up being white-ish.
