Sorry, I had to post this again since when I tried to change images, even logged in as host, I couldn't get rid of my own PBase ID, thus going against the anonymous spirit of the challenge. Unfortunately I lost all the comments from springishere, sky and frank, whose enhanced color I really liked. I had boosted the reds a bit, but the blue does make a difference, so thanks, Frank!
