Hi, BBDad!
You do have an interesting little guy, don't you? Fascinating.
The only thing close to this that I know much about is the late nineteenth-/early twentieth-century Russian composer Alexander Scriabin, who associated pitch with colour. At least one of his pieces (Poem of Fire) has a part for a "colour organ"; it had a regular keyboard, but instead of sound, it projected coloured lights onto a screen as the rest of the orchestra played. (I believe Rimsky-Korsakov had similar beliefs, but somewhat different associations of which colours were implied by specific pitches.) Scriabin when he died was working on a huge multimedia piece called Mysterium--it was to be played in the foothills of the Himalayas, and there were to be music, dance, colored lights, and perfumes--and at the end, the world was to dissolve in bliss....I think he had some association with theosophy and Madame Blavatsky. I don't remember much more than this (he was about a hundred years after "my" time, for research purposes), but it's enough to give you the idea.
I'm sure this is no help at all, but thought it might be a little bit interesting, under the circumstances.
peace
