Pink

Graphic black and gray upholstery and bold jolts of color stand out against the statement-making blush-pink walls of the living room. The oil painting by Croatian artist Stjepan Šandrk pictures a young woman holding a cup of coffee and a cell phone in front of an 1866 masterpiece by Gustave Courbet.

The multipurpose wall is "like a sculpture interacting with the art," explains architect Carlos Ridruejo. "Based on the simple geometry of an exploding square, its design is intended to create interest, not overpower." The owners take pride in their art collection, which includes the bronze sculpture by Pablo Eduardo.
