The season sparkles with colors that surprise. Eileen Kathryn Boyd loves to splurge—on color. The New York-area interior designer’s appetite for striking hues is satisfied by unexpected combinations that have a youthful and energetic style. In her dining room, she stamped her purple-and-green signature design palette on a formal table that serves up a lavish and glamorous presentation for any holiday gathering.

As a modern alternative to conventional placemats or runners, Boyd cleverly cut a roll of purple paisley wallpaper to frame each individual setting. “It’s a great way to customize a gathering,” she says. “You can get specific patterns and colors, and one roll is the perfect amount.”

Rectangular hammered silver trays sparkle from beneath creamy silk scarves. White dinner plates with delicate gold flourishes top sharp, apple-green service plates.
