I used Repose gray in several rooms in my house because its a warm gray. I also have Mindful Gray, which is just a little darker, in the great room. It's a little bit from the green family compared to some other grays, but on my walls, depending on how the light hits it, it can read light blue sometimes. It is a really nice color. I also had it in the kitchen above a cooler white cabinets, and it looked dirty. So we switched that to Gray Screen, and it looks just about like the repose gray in the rest of the house.
I would suggest painting a few big poster boards with the colors you are considering, and move them around the house to see what you like. Also, I would probably have to have all the other things in before I could pick the right color, but that's just me.
