"Aqua is elegant and flattering. You feel pretty in this bedroom, and pretty never goes out of style." In the master bedroom of this formal Long Island home, Tiffany blue walls — Benjamin Moore's Blue Bonnet — are a cool counterpoint to the deeper hues in the fabrics, from Scalamandré's Chi'en Dragon for the bed and curtains to Osborne & Little's Limpopo on the stool. Vintage swivel chairs are covered in Kravet's Soleil. Table lamps, from Circa Lighting, sit atop bedside tables from Oomph. The bed linens are by Jane Wilner.
