Hi Dianna,
Stanley Burrough, the guy behind the Master-Cleanse wrote also a book called Healing for the Age of Enlightment. I didn't read it, but as far as I know he gives there a descriptions of 9 colors and how they can effect us. If u want to read more u can for exemple go to: http://www.momentum98.com/colorther.html
It's a commercial site, but u can at least read there some more about this theory. TC F.
