I’m sure there’re many who have cheered up at the sight of a beautiful rainbow stretching across the sky after the rain clouds clear. The colors of the rainbow are actually the colors of the light rays of the sun. Drops of water that catch the light rays from the sun reflect the light, function as a prism, and the refracted light rays can be seen as 7 strips of light. The colors observed varies according to the country, and there are countries that only see 5 or 6 colors. Today, we have a series of illustrations featuring these colorful rainbows. Well then, enjoy!
