Ceiling design can vary with Straight Ceiling, Vaulted, Semi-Vaulted, Tray, etc.
Wall design also could be plain plainted, papered, 1/2 & 1/2 chair rail colored, bi-colored, wainscot, vertical or horizontal, tongue and grooved, panelled, etc.
If painting, don't rely on color charts alone! Get small samples and let dry on the wall to see the true "dry color" of the chosen paint. The greatest disappointment is relying on color charts. Probable 60% error.
