I would go with these new popular Benjamin Moore colors:

I have to agree, gray is an excellent choice for wall color. Our walls are gray now downstairs and we get so many compliments. Colors only made our small (650 sq. feet downstairs) space feel even smaller. Gray has a nice way of warming up the walls without being noticeable. I think once you 'look' at the walls the space feels small... especially if it really is a small space.
This is the color of our living room:
Edgecomb Gray Some examples of rooms in that color:
(above photo... the edgecomb is the color in the stairwell)
Then, our kitchen/dining room (which butts right up to the livingroom) is painted in
Silver Fox
edited to add... my cabinets are cherry in color and the silver fox looks great with it.
