Interior designer Pamela Chelle loves color—from petal-pink bathrooms to lipstick-red dining nooks—but not every client shares her passion. For this new Washington Park home, bright hues were a definite no, but making a statement was a must. Chelle’s solution? Contrast. The principal of the eponymous design firm paired traditional wainscoting—painted Benjamin Moore’s Simply White—with Schumacher’s Fern Tree wallpaper in Graphite. “It’s modern and graphic, but softened by that organic, botanical motif,” she says of the stylized diamond pattern. The trick to pulling off such a bold choice: restraint. Chelle paired the paper with various textures—reclaimed-wood ceiling beams, Kichler’s polished-chrome Erzo chandelier—rather than additional patterns; chose clean-lined furnishings, including Mitchell Gold & Bob Williams’ sleek Remy dining chairs; and stuck to a palette of quiet neutrals. “A pattern like this makes the room,” Chelle says. “It’s busy and beautiful enough”—no bright colors required.
