Hampton Designer Showhouse

Hamilton's own version of happy is a cheerful palette of complementary colors, green and rose, with accents of sunny yellow and a few other garden-variety hues thrown in for a multifarious mix. Green is expressed mainly through an Osborne & Little wallpaper that's "a dizzy contemporary version of papers from the period between the wars in Britain," says the designer, while rose is articulated by the Hazelton House chintz draperies and the China Seas tufted fabric on a Phoenix Custom Furniture chair.
