When examined closely, violet usually appears on the bottom of the rainbow because it has the shortest wavelength of light and bends the most while it passes through the water droplets. Many spiritual individuals believe the Rainbow when spotted, is a sign of luck, hope, promise, new beginnings, and eternal life.
The multicolored arc-shaped phantasms are beautiful traffic stoppers and believed by Christians to be symbolic of the covenant God made to Noah. Because sunlight is composed of several colors, when rays from the sun exit the water droplets, they are separated into all wavelengths, or colors of light that reflect in the sky as a Rainbow. Rainbows typically occur after the rain when wavelengths from the sun enter floating water droplets in the air.
