Details: This poster shows a rainbow colored umbrella against a gray background. At the bottom it says If You Want The Rainbow, You Gotta Put Up With The Rain. -Dolly Parton.
Rainbows are optical and meteorological phenomena that cause a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. They take the form of a multicoloured arc, with red on the outer part of the arch and violet on the inner section of the arch. The rainbow has a place in legend due to its beauty and the difficulty in explaining the phenomenon.
