Bernard Aubertin is known for his monochromatic red paintings. For Aubertin, the red paintings create a depersonalized, mediated experience: they symbolize fire and blood, while at the same time allowing him the space for anonymity. A member of the experimental Dusseldorf Zero Group—founded by Heinz Mack, Otto Piene, and Günther Uecker in 1963—Aubertin reacted against Art Informel and Neo-Expressionism and was interested in developing a new art rooted in international collaborations, concepts, and ideas.
