We are looking at buying a house that has vaulted ceilings in the kitchen and living room. I want to paint my ceiling and one wall, in the living room, similar to the pic below with the blue wall. Maybe not quite that dark.

As you can see from the bottom 2 photos, it is not an open concept, but more of a doorway between the kitchen and living room, causing a separation. I was thinking of blue and dark tan/gray colours for the living room, but am at a loss as to what to do in the kitchen. Any ideas? I don't really want to go with a white ceiling in the kitchen if the living room is a blue ceiling. And given the cupboards and the kitchen being small, should I just paint the kitchen and ceiling all one colour? Maybe the tan/gray that is also going to be in the living room? Thanks a bunch for any suggestions.
