A cozy and dark library greets guests as they come through the front doors. Although a bold black-and-white palette can come across as harsh, principal interior designer John Day and associate interior designer Jayme Kennerknecht carefully mixed in warm accents to create a softer look."White is typically cold, and black overpowering," says Day. "But with added touches of rich, deep colors, plus careful changes in texture and pattern, we were able to warm it up and provide balance to the high-contrast theme."
