The shade of gray color that you choose can either make a room appear bigger or smaller. To make a room look bigger, rather choose a light gray color that will give the feeling of openness and more space and then pairing off the light gray with a neutral color such as white or beige will not only make the room appear calm but will also add a level of sophistication. To make a room appear smaller or cozier, the darker the shade of gray color used, the better the result.
