To add drama and depth, work on painting one wall a deep, intense tone - this gives it the impression of being further away along with adding an unusual charm. Pale colors will recede, therefore making the room seem larger and blueish gray is a great decorative paint color for a small room. But then if that sounds too colorless, dont despair cool colors like blues, greens and purples also recede so you can use your beautiful shades without making the room appear small sized.
Choose a pattern or not: In some dining rooms the area rug serves as a floor covering that feels good underfoot and is meant for function and not décor. While other dining rooms keep a simple table and chairs, and then have the area rug take command of the room. If you choose the more bold approach, choose a few colors from the carpet and bring them into the wall color and fabrics of the room. This will unite the room and keep it from looking too busy for the eye.
