I managed to prime and paint yesterday. Here's one of my Rothko-esque (but not really) looking sample spots [I apologize for the lighting. There's not much I can do about it.]:
In order from top to bottom: Pearl Harbor, Barley, Malton. We've pretty much eliminated the barley. It's even more yellow than it looks in this picture. Pearl Harbor is much richer than Malton. We're going to paint bigger pieces of the walls with those colors and see what we think.
