The easiest, least expensive way to make a big change in a room is with paint — especially darker hues. Inky blues, rich greens, charcoal grays and striking aubergine feel especially current and can be found in hotels like the Crosby Street Hotel, the Greenwich Hotel, J.K. Place Capri, the Vidago Palace (above) and the Jerome. Dark bedrooms create a cozy, cocooning effect. In a living room, deep hues can be entirely unexpected and create a fantastic backdrop for brighter upholstery or art.
