Many of my clients have a hard time picking wall colors when their home is filled with natural wood: window and door trim, baseboards, hardwood floors, not to mention the furniture. First, I avoid yellow-orange and most red tones. Isn't there enough of that already? Consider green and blue undertones. They usually work. Think nature. Grays are also nice. All of these colors help cool down all the yellow-orange from the wood. I've heard many times, "I wish I had white trim." Assuming your wood trim is just run-of-the-mill, there's no reason you can't start with painting the trim in one room and leave the other rooms for the next renovation. Another option is to stain the trim very dark to turn it neutral and give it a more modern look.
