Black is not a color that first comes to mind when you are looking for a color for your walls. Tell someone to paint a wall in their bedroom black, and chances are they'll think you're mad. Why is it that we don't use it in our homes? You may avoid it for religious beliefs, but beyond that do not shy away from using black because someone said that it makes the space look smaller??
Black is bold. It is a statement color. It has character and a universally acknowledged panache. Do it the right way, with the right materials, the right techniques and in the right places, and you will surely be a home decor trendsetter.
