Thanks so much - I never expected to get so many replies! Working a variety of unexpected colors into paintings is something I am trying to acheive, rather than just duplicating local color.
It seems to be not uncommon for some of us to have a very literal approach to painting. I applaud your efforts to loosen up and find new color interpretations
Lamar - Your kind comment really made my day. I do not believe I have received applause for anything, except perhaps leaving a room. Interpretation of a subject is very challenging for me, as I don't want to just be a copyist. But then the perfectionist in me wants to get things "right". No one I have met is trying to "tighten up". My memory of the quote in the movie Art School Confidential may not be spot on, but there is a scene where John Malkovich's character proudly points to a lone solid black triangle on a white background. He then stated, "It took me years to learn how to paint like that."
