I believe that color affects us in ways we're not even conscious of most of the time. People react to and experience color much like music. It is a language of felt experience, memory and emotion. I paint quickly with layers of colors that push or move me. I can tell that one of my paintings is finished when I stand back and squint my eyes. If all the colors work with or even against each other to keep my eyes  searching  for the next "great moment" then I know I've created a playground for the eyes.
