Fauvism

Name derisively hurled at and cheerfully adopted by a group of French painters, including Matisse, Rouault, Derain, Vlaminck, Friesz, Marquet, van Dongen, Braque, and Dufy. Although fauvism was a short-lived movement (1905-1908), its influence was international and basic to the evolution of 20th-century art. It was essentially an expressionist style, characterized by bold distortion of forms and exuberant color. From encyclopedia.com
