‘While the painter’s mark indicates passion,” an artist I know recently said to me, “shape points to pictorial intelligence.” Lee Krasner (1908-1984) possessed an abundance of both. A superbly cool, concise, complete and—most important—compelling exhibition of her work, “Lee Krasner : Living Colour,” is now at the Schirn Kunsthalle Frankfurt. And it makes the case for Krasner as not only a major Abstract Expressionist, but also an artist whose oeuvre—35 years after her death—argues for the continued vitality of abstract painting in an era of increasingly synthetic and electronic art.
