Born at the dawn of the 20th century, Fauvism burst in 1905 Salon d'Automne with a resounding scandal. It was like throwing colors at the face of the academic art entangled in its ancestral conventions. Then several artists, like Matisse, Derain or Vlaminck, searched for a new chromatic language by diverting the color from its signified. Freed from any connotation, applied in flat tints, the color, they claimed as their only standard, impregnated their stunning paintings. The author invites us to this ball of vivid and bold colors, and shows us how the violence of the Fauves left its mark on the path to modernity.
