It was a hot and sunny day in New York, so I bustled my way to Central Park to do some painting. As I mentioned earlier, I brought only four colors on this trip — red, blue, yellow, red oxide — pus white. With that palette, it was hard to get some of the bright greens in this scene, but it sure was fun to try. I can see why some people advocate a limited palette: it makes you think more carefully about mixing paint. Anyway, I did this little sketch in about two hours, with the tiny 6” x 8” panel propped up in my little Guerilla Thumb Box.. I sat on a bench until the sun bore down on me, then stood behind a tree, then sat on the ground. Meanwhile tourists bustled all around me. Challenging circumstances!
