After much pondering, I'm now thinking of going with a very pale green. I think it will complement the view of the tree tops outside and add a touch of "freshness."
Yep, our downstairs TV (surround) room had a chair rail around the wall its got a pale off white above it and I painted below the rail a pale green - very soothing and nice when the main light is off and lit with indirect light for movies. (I did a crown molding and laid rope lighting behind it for dim ambient light when listening to music or watching movies ..)
