Welcome James. Your background and amazing capabilities with so many languages, is bound to be a very richly rewarding experience for our community. We do look forward to your valuable contibutions.

Jim,  I suppose what I was thinking was using various notes of the music scale as the pitch for the voice as the sounds you suggest are chanted or entoned - whichever way you choose to express that.  And as there are specific musical notes generally associated with each color, then I shall start with those.  So following your routine the color'-tone associations I will use will be:

White light - not sure what tone to use! I'll research that further....

Red light - C

Blue light - G (Indigo - A)  so it depends on which blue you mean

Yellow (yellowish gold) - E

Green - F

One reason I was curious about your choice of colors was that normally green is associated with the heart chakra, blue with the throat, indigo with the brow, violet with the crown, red with the root, orange with the sacral, and yellow with the solar plexus.    At first I thought perhaps you were using the complimentary color of each chakra, in order to bring balance, which is a valid idea, also used in astrology;  and alchemy, I believe, although I'm pretty much a complete neophyte when it comes to that subject.

Anyway, that's how my thoughts on all this were running. :-)
