A synergy of image, color and sound greets the viewer to the Nelson-Atkins Museum of Art’s special exhibition, “Napoleon: Power and Splendor.” Replicating the ruler’s so-called “Imperial Household” are flooring designs recreated from authentic carpets. Walking from gallery to gallery, against backdrops of rich teal blue, burnished burgundy and forest green you encounter dozens of paintings, sketches, mosaics, architectural drawings and panoramas by Napoleon’s court painters.
