Because of their colorful and unique display, rainbows have generated countless legends and myths throughout history. Among the most popular is the Irish folklore that leprechauns store their pot of gold at the end of a rainbow. But the truth is, rainbows can be seen only if you are in the right place at the right time.

If you’ve ever seen one, consider yourself lucky. For a rainbow to appear, the conditions must be just right.

Rainbows can be seen when light passes through raindrops, says Kristin Calhoun, a research scientist at the National Oceanic & Atmospheric Administration (NOAA), the scientific agency focusing in part on the conditions of weather.

When a person sees a rainbow, it’s really an optical illusion created by the refraction and reflection of light. An optical illusion is when you see something that appears to be something other than what is really there.
