A rainbow is a meteorological phenomenon caused by the reflection, refraction, and scattering of light in drops of water, resulting in a spectrum of light that appears in the sky and takes the shape of a multicolored circular arc. A rainbow is not something that can be touched or approached. It will disappear at the wrong angle. It is possible to see rainbows in the dew, fog, spray, mist and in the rain.

Because a rainbow is created by light shining through water, people see it differently depending on their point of view.  So this means, every rainbow is unique to you!
