Clever painting is all about illusion and choosing wall paint for small spaces is the epitome of this concept. Gone are the days when the only color that could possibly used as wall paint for small spaces was white. Apart from appearing too stark, your wall paint for small spaces will be far more effective in one of the subtle shades, allowing you to add tone and depth to your chosen color. Dove grey, or a blue-grey is a perfect foil for a small room, although soft heather or a hint of green would be equally effective. There are other things you can do when applying wall paint for small spaces: paint the wall directly opposite the door a deeper hue of your main color — this will give that wall the appearance of receding further back, thereby opening the room up and giving the illusion of space.
