During their decade-long collaboration (1985-1995), Kate Ericson and Mel Ziegler produced some of the most influential conceptual art projects of the time. Among their witty and stimulating installations and outdoor projects was Camouflaged History, a house painted in a U.S. Army-designed camouflage pattern using 72 commercial paint colors included in the municipally-approved "authentic colors" of historic Charleston, South Carolina.
