When designing a room, it's easy to get caught up in the idea that everything has to match. Using different tones and textures, though, is often what gives the room its appeal. The brushed nickel knobs in this dining area are a nice contrast to the dark curtain rod, floor and light fixture. While a light curtain rod on the light wall would have worked here, the effect of this rod is that it carries a hint of the deep colors in the adjoining room over, creating a cohesive look.
