Leather is dark. I know...hello, Captain Obvious, but stick with me. Leather itself is heavy, and that translates into your design. So...how do you lighten up your design? Add light and white tones, of course. I love these spaces. They are a great example of how a dark, leather couch doesn't have to make the entire space look dark and heavy. The leather doesn't control the room. It's all about balancing color, textures, and even materials. I, of course, love leather with black and white, because, well, I love natural neutrals (i.e. woods, leathers, natural fibers, etc.); I love black and white; and I love mixing the two. Give it a try. Show that leather couch who's boss!
