The walls of Bruce Silverstein Gallery are painted Van Deusen Blue, a historical color from Benjamin Moore.
"The vast majority of colors shown on Benjamin Moore & Co.'s Historical Color Collection cards are from the files of the National Park Service in Philadelphia, PA. These colors were obtained by stripping down through multiple layers of paint and then matching with Munsell designations. Penelope Hartshorne Batcheler, a historical architect with the National Park Service, and a specialist in historic paints, was the pioneer in analyzing and matching these colors."
I really felt I needed to go with a historical color AND a blue found in the wall murals... as well as a warm blue. I thought about it a lot and NAILED it with the color of the walls.
