Franz Kline - Black on Green Red and Yellow, 1948

From Wikipedia: "As with Jackson Pollock and other Abstract Expressionists, he was labeled an "action painter" because of his seemingly spontaneous and intense style, focusing less, or not at all, on figures or imagery, but on the actual br...ush strokes and use of canvas. For most of Kline's [mature and representative] work, however, as the phrase goes, "spontaneity is practiced". He would prepare many draft sketches – notably, commonly on refuse telephone book pages – before going to make his "spontaneous" work."
