Amazing how so many musicians with chromesthesia use the colors to write their music! That's so sad Vincent Van Gogh's music teacher thought he was insane. :(
I browsed Wikipedia for more on synesthesia after reading your article The closest one I could relate to as a non-synesthete is number form: I have a spatial sense of numbers. It's frustrating though because I couldn't draw you a map of how the numbers look. They go in a slight curve and seem to twist in a new direction a few times between 0 and 100, but I can't clearly visualize it or pin it down.
Thank you for introducing me to the fascinating subject of synesthesia. It makes me want to explore my senses more and see what I could do to encourage more collaboration or intersection between them - which would probably improve my memory. Enjoy your gift as a chromesthete - well, I know that you are. :)
