I recommend that you consult an interior designer or window covering professional. In addition to color, you need to consider stack heights of the various blind options and other little details that a professional can point out for you. If your blinds are going to be down all the time, stack height doesn't matter. But if they are going to be raised, then stack height and mounting location become important. We have transom windows and want our blinds to be up during the day. If we had gone with wood blinds, the stacks would have covered the transoms entirely when up. Good luck.

I thought I'd mention one more thing. I don't think that this applies as much to wood blinds, but we had dark brown aluminum blinds in one room at our old house and they were a nightmare to dust--always ended up with dust lines if tried to just dust and would have to use a wet cloth slat by slat to make them look nice--very time consuming on big blinds. Lighter colors don't show the dust like dark ones do. We have always used Hunter Douglas blinds, cellular shades and pleated shades and have always been pleased with that brand. We just used pleated shades in the upstairs rooms of our new house, and the fabic on all 15 of the pleated shades were defective, and it was very easy to get Hunter Douglas to replace all 15 of them. Hunter Douglas is probably a little more expensive than the other brands, but I have been very satsified.
