Blue & white may be the best color duo in decorating -- it works in a range styles and shades while always looking fresh and inviting. We went to the Massoud collection for a colorblock wing chair, sleek tufted sofa, leather-top ottoman (love the lift-out tray!), and botanical-print slipper chair. A reversible rug defines the seating area, and a wall gallery of prints enlivens the bookcases. A white ceramic lamp with dark blue shade completes the look.
