I don't really know about color matching into your TV Credenza, it's too hard to tell from photos. They would be on the other side of the room, so coordination would be more likely rather than matching. As long as they are not radically different (such as a bright red)you are usually pretty good to go. I would get two for sure, whatever you decide upon.

Crocks can be collectible - there is a whole sub-culture that is into collecting those. Take the money...and RUN !
