The color blue made a splash in this blue-ribbon exhibition featuring all things blue from the Concord Museum’s wide-ranging collection. Fashion and furniture, tableware and textiles, art and advertising lit up the galleries with a blue palette that was both hot and icy cool. This exhibition looked at objects from the Museum’s collection through a blue lens, exploring the pigments, fabrics, papers and paints used in seascapes and landscapes, geometric and floral bandboxes, charming coverlets, always-appealing blue and white ceramics, a Union officer’s great coat, a 1960s Emilio Pucci patterned silk dress, and much more.
