i patched awffull to give it ability to read user's personal colors in awffull.conf and draw personalized charts. The patch has been made on awffull-3.02-beta2 but Steve McInerney have just released the 3.02 version today (not beta).
He told me he will include the patch for the next release (3.03). If you can't wait, you can get my patch here (applies on 3.02-beta2).
Update: this early patch gave not full color customization, the next official awffull will handle it better.
