Larina Kase picks white shades according to her clients’ style, with the help of a design quiz that helps her home in on the right hue. “Light levels and floor color” are important considerations when choosing white shades, explains Kase, “A floor with honey-warm tones can reflect and make the walls look more yellow than desired.” While the perfect pick takes a bit of artistic detective work, she favors white paints from Benjamin Moore, including Super White, Chantilly Lace, White Dove (pictured here), Decorator’s White, Vanilla Milkshake, and Steam.
