I have grapheme-color synesthesia. In my case, this means that I perceive numbers as having innate color properties. For example, 5 is an orange number, 6 is red, and 7 is blue.
Sometimes I see (or think of) a number, and it gets stuck in my head like a melody. Those are the numbers I’ve been painting.
I never knew. These are really interesting pieces. I dig the style. You should set up a One Woman Show somewhere. Somewhere with a math cross over would be great. National Math Archive?
Funny how you can know someone for years and miss a major bit like this.
