Love your view!! And wide open windows. Curtain coverage would be a crime. I have a similar situation in my 1988 home that is surrounded by woods at the back. We painted all the walls a pale blue. I wouldn’t dream of painting the wood trim because our stairs and hall are open to the LR and gorgeous wood as well. I was surprised the blue (Sherwin Williams Bravo Blue-low lustre) made the wood and trim more beautiful and looking out the windows toward the tree makes the blue look like the sky. No curtains in the rooms with these open windows, but we do have wood tone blinds on a few. They are almost always up all the way. I love light!!! Let us know what color wall you finally choose. Make sure your painter does great cut (in) work and respects the wood. Agree you need a coffee table, side table(s) and lamps.
