Sushi,
I also went with the maple/tan combo for my QS8's only (have black speakers and grilles for M22's and VP150), and both my wife (all important) and I have been pleased with the look. Axiom actually sent me the black grilles by mistake at first, so I had both in my apartment for a time.
The black looked fine, but since we wanted the surround speakers to blend into the surroundings, at least as much as the QS8's can blend into your living room, we preferred the tan grilles and that's what we stuck with. The tan has somewhat of a peachy tint to it, which is the only minor problem with it. But, all in all, the tan grilles are a viable option to pair with the maple speakers if you want them to be less obtrusive than the black grilles.
