Work On The Natural Lighting

Some areas in your house could be dark simply because there is no way for the natural light to go in. If you do not have any windows close to the dark area, try to create one. In some other cases, the window is too small to bring sufficient light to the room. The bigger the window, the more light that gets to your house. You could also try cleaning the panes on the inside. If long branches are covering your windows, trim the trees around your home for sufficient light.
