Neutral color schemes get a bad rap. Too many model homes with drab walls and matching carpets may be the culprit. Decorating with neutrals can be a very chic approach to a room, you just need to create enough interest in the space so it doesn't put you to sleep.
Use contrasting textures, fabrics, and shapes to keep a room dynamic. Introduce small pops of color in artwork and accessories. Vary the shades of a similar color throughout a room, and use pattern to keep the eye moving throughout the space.
