Tasteless Rainbow of Smut

Along with this reflection is refraction of light that causes of a spectrum of colors-- red, orange, yellow, green, blue, indigo and violet. Certain angles and "bending" reflect light better for refraction to occur, and the amount of light refraction corresponds to wavelength and color. While a primary rainbow is visible when light is reflected once off the back of a raindrop, a secondary and usually dimmer rainbow is spotted when light is reflected twice in a more complicated pattern.
