When you're trying to determine what kind of lamps to have in a living room, consider both the height of the lamps and the color and style of the shades. By working with all these elements, you can achieve a look that has unity without being boring. For example, choose two floor lamps that are the same height, and choose shades in the same size and shape but in different colors. Or, choose a floor lamp and a table lamp, each with identical shades, perhaps with the table lamp's shade a smaller version of the shade on the floor lamp.
