Finally, at ZINC contemporary, a group show whose title speaks for itself: Color Cure (through June 26) is a showcase of abstract works that emphasize the virtue of hue as “a remedy, a salve and celebration of the human spirit.” Among the six artists included are Seattle-based Barbara Robertson, whose blocky shapes vibrate with bright geometry, and Chicago-based Martina Nehrling, who plays with the “emotive slipperiness” and “controversial decorativeness” of color. It might be just the thing to celebrate the emergence from our caves.
