The drawings and sketches of Stanley Whitney are permeated by the ghosts of Cézanne, Munch, Morandi, and Matisse. Whitney’s drawings are lighter, airier blocks of color than his larger canvases and are small treasures of rhythm, balance, and harmony. With Whitney, everything begins and ends with color; his drawings and sketches are delicate and exquisite studies on the possibilities of color on paper. At Lisson Gallery through October 21.
