Black & White
Black and white rooms are timeless and never go out of style. They're classic, as well work really well for all types of rooms. Whether it's the bedroom or the kitchen, black and white walls are a for sure thing.
To keep it interesting play with texture for example a faux brick wallpaper like the image above (available at Colournow). The change in texture will ensure the room doesn't fall flat by creating architectural details.

In the kitchen try to add some depth by choosing a set of cabinets to paint black, whether it's the island or pantry the contrast of black and white is sure to wow.

The washroom can handle the bold look of black and white as well. It's poppy and fresh as well keeps a neutral style that is both masculine and feminine. To help with smaller washrooms use more white paint or accents than black to keep it open and bright.
