Fauvism

André Derain: Boats At Collioure (1905)
Wikipedia - "Fauvism is the style of les Fauves (French for 'the wild beasts'), a short-lived and loose group of early twentieth-century Modern artists whose works emphasized painterly qualities and strong colour over the representational or realistic values retained by Impressionism. While Fauvism as a style began around 1900 and continued beyond 1910, the movement as such lasted only a few years, 1904–1908, and had three exhibitions. The leaders of the movement were Henri Matisse and André Derain."
