Having just the right indoor lighting can make a difference in the look of a room.  I think most people notice light fixtures.  I know when our daughter and s-i-l added contemporary light fixtures to their house, they received comments on how nice they looked.  Old, outdated light fixtures can help to make a room look outdated.  But new ones, along with new paint on the walls, can give a room a whole new look.  It really does make a difference!
