I'm not really sure, I've just always loved warm colors. On the way home from work, the train passes over a bridge that overlooks Boston, and it's usually around sunset, so there's just all types of crazy colors dancing around the buildings and off the water. That could be one inspiration I guess
I guess the music I listen to does it as well. I don't know how to explain it, but I listen to a lot of beat-heavy stuff, and it creates visuals in my head.
