In the 2nd picture, I'm standing at the entrance to the living room from the hallway. The fireplace/panel wall is on the right side. The wall on the left is one of the two long walls of the rectangular living room. So, one of the long walls would be paneled, the other would be the accent wall, and the two short walls would be tan maybe?
I talked to my DH, and he likes the idea of the sage green. We got some of the little paint samples, so we will take them over to the house tomorrow and see what we come up with!
thixie - I'm glad you're loving your paneling! I think I will really like mine once we get everything set up.
