A Bauhaus-inspired palette of yellow, deep green, and blue take this transitional living room in a rented townhouse from ho-hum to heavenly. To stand up to the goldenrod credenza, vivid green marble coffee table, and forest green upholstery, a large, colorful landscape painting takes center stage. Without making any permanent changes that would have to be undone later, bold choices in art and color make this temporary house a spectacular home.
