What is the meaning of a Rainbow Aura?
A Rainbow Aura is a very positive sign, associated with paranormal abilities and enlightenment. It represents the aura surrounding psychics, mediums and other spiritually advanced people.
It also involves an aura of colors "brighter than bright" surrounding such a person - brighter than any rainbow!
 The color spectrum of that light permeating around someone who possesses this sign can shift to include brilliant white and gold in addition to the more usual colors seen in our normal world.
