You can try
http://www.subaruparts.com/diag/?mod...ategory=660B-1. They don't list specific colors, and I couldn't find all of the wood parts, so you'd probably have to call to get that information. Looking at the prices though, you'd be spending $500 or more to swap out the wood trim.
A cheaper option would be to find someone that is parting out a car that has the pieces you want.
