Try a color and if your wife doesn't like it, paint over it. After all paint is the least expensive thing to change. I really think bold colors make a room look inviting and warm. Go to a paint department and get lots of samples. I always get about 10 each of the colors that I am contemplating. Then I tape them together and affix to the wall and stand back a distance. Leave them up a day or so and let the colors 'grow' on you...or not! Keep us posted, OK?
