In this Manhattan home, I crafted a sophisticated, soothing environment for the bedroom: a neutral color palette with minimal decor, but enticingly glamorous — the textures of the luminous, mother-of-pearl bed finishing, the lustrous faux-alligator wallpaper, and hemp-and-silk rug make the statements in the absence of color. Bolder tones take the lead in the rest of the apartment — mixing color, pattern, and texture to make each room an individual experience.
