pamcoy, brown is a great natural and neutral color, but (without having seen your particular situation), I would suggest that you carefully consider this color, as it may prove to be too dark for your great room - a space that I assume is used all the time by your family and friends. It really depends how many large windows there are, the exposure(s), the ceiling height and how much wall space the room has and all of the other elements that are/will be in this space. It also depends, of course, on the particular color you select. Are you working with an interior designer or decorator? If not, find a good one and work with him/her to achieve the best results.

I have very little wall exposed and i do have 5- 70"l windows and a large opening to the foyer with glass door with transoms, i believe it will be enough light
