From some of the posts here, Lexio can come with a a surprising (and unexpected) assortment of colored tiles.
My copy of Lexio White, from Boulder Games, was missing a tile (with a duplicate of another). Marking it with a Sharpie was out of the question, since I bought this game partly for aesthetics. (And it really is beautiful.) Although by the time we received the game it was out of stock at Boulder Games, they managed to track down a replacement piece and send it free of charge.
Kudos to Boulder Games!
