Bonelli-Steel-Windows-Mill-Valley-Remodel-Gardenista Above: In this Mill Valley kitchen remodel, architect Brett Terpeluk, of Studio Terpeluk, added floor-to-ceiling casement windows, which flood the kitchen with natural light. Originally, the idea was to have custom window frames made of blackened steel with a wax finish, but the clients opted for a low-maintenance–and less expensive–alternative: Bonelli Series 700 frames of anodized aluminum with a bronze finish.
If your home is predominantly stone, brick or some other material that isn't painted, you can select the right accent color by pulling out a color that exists in that material. For example, if your stonework has a soft pale green hue scattered throughout, selecting that color for details and trim elements can be quite nice. Just stand back and survey the material, looking for those spots of color you notice and want to bring out.
