Right now my speakers are all 5 different finishes.

On-wall M22: Standard vinyl Black
On/in-wall VP150: Custom vinyl Warm Cherrywood
Bookshelf M22: Standard vinyl Boston Cherry
EP350: Custom vinyl Cinnamin Beech
Bookshelf M2: Real wood finish Cherry Nutmeg

If I ever buy surrounds, I'll probably get them in the same finish as the M2, Cherry Nutmeg. If I ever buy M50's, I'd probably go with Cinnamin Beech to match the subwoofer.

Decisions, decisions. I feel for you.
