When designing a dining room, it's often easiest to start with one simple decision: dark and dramatic or light and airy. Once you've made that decision it narrows down the paint color decision. If you're going for the light and airy look — stay in the white, beige or even light gray familes.
Going with a light wall color really frees up the decision for the dining table. Any tone will work — it all depends on the ultimate look you're going for. White tables really put the icing on the light filled dining room look and allow for color to be added through accessories and chairs upholstery, while darker wood dining sets create a dramatic juxtaposition.
