Wolf Kahn is a German artist who loves to draw colorful nature scenes with chalk pastels. Though an old man now, he tries to make his art look like a child created it. His favorite pieces are ones he did when he was a young boy – where color didn’t have to represent reality. First graders made watercolor and oil pastel resist paintings of trees in Wolf’s style – and, since they are kids, they chose which colors they used. The one rule was to draw the trees with analogous colors, or colors that are neighbors on the color wheel.
