I've got Sorrel Pear, Warm Cherrywood, and Cinnamon Beech in front of me right now. All three are very, very similar in color/darkness. The main difference is grain structure. All are MUCH lighter than the Boston Cherry. (which all my speakers at home are)

If you're trying to match something darker than the Boston Cherry, I wouldn't bother getting the above mentioned samples...though very beautiful, they're not dark.
