Be bold and make a statement. Change the color of one of your walls or even wallpaper one wall if you want a contrasting design. Rich, dark hues can transform your space and add life and depth. The area will draw the eye so take some time to consider your color choice. Artwork can really pop against the right background. One wall is not too daunting and can be painted in a weekend. And it is only paint. It can always be changed later.
