I interviewed Tonya Gamman this morning and put the recording on the course page under Additional Links and Resources. You can also access it here:
http://www.angelfire.com/...aGammanInterview.mp3 Tonya is a healer who uses several modalities, including color therapy.
She also has written a book "Heaven and Earth: How it all Works" about her memories of heaven and says that they use colored light to heal the etheric body in heaven.
She has some interesting comments on how to heal with color, what colors not to wear, and using the violet flame with healing.
