Bill. I was thinking of Bob Fulton as I read this. Years age we had a small dealer in San Diego who sold Fulton products. Fulton visited a few times to give demos or talks. As I remember it he assigned a different color to each instrument in a typical symphony orchestra. Then he would say "that trombone doesn't sound purplish enough", or whatever color he described. At one time I had a copy of his color chart but that is long gone and I don't remember the details.
As well as designing and building loudspeakers, electronics, and wire he made recordings of local music groups. They were decent recordings but amateur talent.
As another connection with music he designed mouthpieces for brass instruments. A friend in my alumni club was in the marching band in college and later the alumni band, playing trumpet. No idea how we got on the subject, I may have ask my friend about Fulton since I'd heard that connection. To my amazement my friend said he played a Fulton mouthpiece.
