Her palette combined pale green on yellow-white — in classically ­layered toile de Jouy from Brunswig & Fils and a ­geometric rug of her own design — with polar white accents: Saarinen side table, painted moldings and fireplace, snow-white ­coverlet and monogrammed ­pillowcases. Touches of hot pink — a ­Hickory chair upholstered in a custom zebra print, tasseled Houles trim on a pair of vintage slipper chairs, books on the bedside table — add a nouveau preppy edge.
