George Sumner (born Aprıl 29,1940) is an American oil painter and environmental activist who began his career by creating marine-themed abstracts in the 1970s. Sumner's painting style appears similar to airbrushing, but he applies oil paint directly to large canvasses with baby diapers prior to blending and layering. His palette of high contrast colors often includes deep blue-green-orche or pink-violets-ruby, which are frequently lightened with pure or slightly off whites. Common subjects and motifs he has returned to over the years include sea caves, coastlines, starfields, whales, dolphins, sea lions, jellyfish, volcanos, butterflies, Golden Gate Bridge, San Francisco Bay, fog, hummingbirds, dragonflies and grape leaves.
