As you can see in this image from when we looked at the house originally, the livingroom has cathedral ceilings and is a sage green. We liked the sage green and wanted to stay with that, but we needed something to open it up a bit. My cousin who is a professional painter, recommended painting the ceiling white again and separating the color at the fireplace. We decided to go with an offwhite in the bathrooms like they have both been initially after treating the walls for the mildew issues.
I think it looks a lot better now, and much fresher. We'll see how it handles the next round of renters...
