Fauvism was a style of French painting from 1898 to 1906 characterized by vivid, raw colors applied in broad flat areas. Led by artists like Matisse, Derain, and Vlaminck, Fauvism emphasized spontaneity and expressiveness over realism. It was influenced by Post-Impressionism and a teacher, Gustave Moreau, and in turn influenced later movements like Expressionism and abstract art. While short-lived, Fauvism marked an experimental shift away from academic color theory towards emotion-driven use of color.
