Style Secret: Traditional PalettesPreppy colors are strong and classic. The iconic color scheme is pink and green, à la Lilly Pulitzer apparel (a prep staple if ever there was one). But navy and red, pine green, mellow gold, and rich and leathery browns are equally appropriate.Updated twist: You don't have to go overboard and drench a room in your chosen color scheme. The brilliant pink and soft green in the bedroom above are balanced by a healthy dose of white to make them feel more of the moment.
