The entire back half of our house has cathedral ceilings with 2 sky lights in each of the three rooms. Years ago, the painter that we had suggested painting the walls S/W Dover white which was the same color as the walls. We did. I liked it. It didn't look "off white" but seemed to tone down the bright factor from "builders' white". When we put our house on the market this past year, the real estate agent told us that we absolutely had to repaint our ceilings WHITE. I had a hard time finding a white that wasn't "glaring or bluish" etc. but finally settled on Glidden ceiling white. Its a soft white. I like it and I am glad I did.
