Well after pondering Round Rainbows I came up with a few ideas. If the Chakras assend from red to purple and red is the closest color to the sun, then possibly the Lower Dentian energy center might symbolize the human sun energy and you would have the rainbow colors working in the right order.

Another application might be in Spring Forest Qigong visualizing the column of energy in the body as a round rainbow starting with the sun in the center.

I'm a application kind of guy.
