We have this high vaulted ceiling that is open to the loft area upstairs.

We are trying to figure out two things:

1- a good paint color that compliments the colors in the kitchen (pale yellow) and our master bedroom (shades of grey purple). Trying to find something in the same tones but we are open to ideas! The thing to also keep in mind is that these walls are all shred with other rooms. We would have to paint the same color in the entry way and upstairs and downstair hallways.

2. How to design/decorate this room. The amount of empty wall space is enormous.
