"Color in Flux" examines how artists have deployed free-flowing color. The works of leading Abstract Expressionist and color-field painters are combined with more contemporary works: among those included are Ai Weiwei, John Baldessari, Willi Baumeister, Lynda Benglis, Katharina Grosse, Kitty Kraus, Joseph Marioni, Bernhard Martin, Paul McCarthy, Sigmar Polke, Jackson Pollock, Gerhard Richter, Dieter Roth, Thomas Ruff and Oskar Schlemmer.
