Thanks guys. I appreciate the comments. It turned out to be more complicated than I first thought too. :-)
SplinterGroup, that blue paint is actually in our house (our office). Her friend's room has beige-ish walls. The bookcase looks good there too, just less contrasty.
Steve, I used my regular blade to cut the aluminum. I don't use my miter saw very often, and I think the blade on it is the one that came with the saw, so I don't mind cutting aluminum with it. I have an old, but nice Tenryu blade on my table saw that I treat more carefully. Do you know if cutting aluminum significantly shortens a blade's lifespan?
