When you blend blue, green, and a dash of gray, you get a shade with great range. "It works beautifully with almost any other color," says O creative director Adam Glassman. "It offsets whites and creams; complements burgundy, mustard, and other autumnal tones; and looks chic with brights like chartreuse." Leatrice Eiseman, head of the Eiseman Center for Color Information and Training near Seattle, isn't surprised to see a gorgeous go-with-anything color take off in this economy. "We want versatility," she says. "But versatile doesn't have to mean boring."
