Synethesia/Chromesthesia- Very interesting!

Yesterday I got out a very interesting book called Digital Harmony: On the complementary of music by John Whitney and I was reading a section titled "The Role of Color and The Role of Music" which talked about colour association with sounds. Interested about this idea, I started  researching it further and I found out that  Synethesia is a neurological condition which means that when one sense or cognition involuntary triggers another. There are many different types of Synethesia but the one I am interested in is called Chromesthesia which is the term for someone who can "see" colour when a tone is sounded. So essentially these people are doing automatically what I am trying to create for my honors project! This could be really interesting if you got someone who had Chromesthesia and played them a track to which they described the colours the "saw" and you could make a video by what colours they saw, that would be a cool test study!
