Long a symbol of good fortune, a rainbow is a delight to the eyes and to the spirit. They occur when light passes through water droplets is bent, or refracted, and eventually dispersed into a continuum of the seven colors of the spectrum. (red, orange, yellow, green, blue, indigo, and violet in that order.) The sun must be behind you in order to see a rainbow. It can often be seen over clouds, waterfalls, oceans, cities, and fields.
