The Vermont Maple is a teeny bit darker than Boston Cherry, but fairly similar. The Warm Cherry is definitely lighter; it's got an orange hue, almost. I haven't seen the other two. The Dark Oak is fairly dark. Hardly walnut, but hey...

However, you should probably get samples from Axiom. They may seem a little pricey up front, but that entire cost goes towards the purchase of speakers.
