We have color.
We did something that we both thought we'd never do, and actually paid somebody to paint. A friend of our drywaller gave us a ridiculously good price to bring in his paint sprayer and spray all of the public areas (dining room, office, living room, stairwell, landing, and all the ceilings thereof) with primer and then roll on paint. Since the dining room, living room, stairwell, and upstairs landing all flow into each other with no breaks, we elected to paint them all the same color, and were able to take advantage of the deal.
We'll paint everything else ourselves, but I can tell you straight up that it was worth EVERY PENNY to have somebody else paint the two-story stairwell, which involved precariously balancing on a plank stretched from a ladder to the top of the stairs. Not my thing.
End result? It looks great, and has saved us a ton of time. Even better, we were able to get this huge amount of space painted before the hardwood floors are in, which makes everything easier. I plan on painting the last of the downstairs spaces - the office - this weekend. It's closed off from the open area, so it'll be a different color, which is why it wasn't included in the deal. It is primed and the ceiling has been finished, though, so it won't take much work.
PS - If you're wondering, the color we chose is Behr's Pecan Sandie, in eggshell. I'm very happy with it - it looks even better in person than it does in pictures, and picks up the natural sunlight we get an abundance of very nicely.
