I would ask on the Home Decorating and/or Paint forums.

Light blue/gray always works for what you have going there.

Congrats on the new home. If the end wall in the second pic can be a solid wall, you might be better served to have your tv centered on that wall (or in one of its corners) and have your sofa (w/sofa table or desk or cabinet or bookcase of equal height behind it) serve as a room divider between entry and seating area rather than having foot traffic forever walking between your tv and your seating area.

Its hard to tell the depth/distance, especially from the wall the dog food is to the back of the sofa. I also feel like you could afford to back up the sofa bit more. I think you could have the best of both worlds in the nook area with bench under the left window and a small table with chairs, you might be able to get a chair and an end table next to the door on the right.
