Orange has a freeing action upon the body and mind, relieving repressions. Because orange is a blend of red and yellow, it combines physical energy with mental wisdom, inducing a transformation between lower physical reaction and higher mental response. Thus, it is often referred to as "The Wisdom Ray." Orange is warm, cheering, non-constricting. Through orange, we are able to heal the physical body (red) and, at the same time, induce within the mind (yellow) greater understanding on how the body may be kept in good repair. Orange helps assimilate new ideas and stimulate mental enlightenment. It is also helpful in dealing with excess sexual expression. Finally, orange links very strongly with the sacral chakra.
