I agree with the others who said to pick a pattern for a place to start. Doesn't matter where you find the pattern, mine came from a border used in the dining room. The dining room got one color drawn from that with the ceiling a lighter form of that shade, and the adjourning living got the reverse light ceiling color on the walls. Couldn't convince my husband that the ceiling in the lr didn't have to be white. So the ceiling and the ceiling medallion are flat white. All the old fashioned wide woodwork and moldings are semigloss white. Good luck, don't worry so much about paint, it can always be repainted in a year or so.
