Maybe you guys can do me a favor.
Take a look at the pictures at this site:

That is a VW Touareg. I really like the look of the interior color on that one. Is the Truffle color similar to that? All the pictures that I have seen on this site make it look significantly lighter in color.
Also, I like the look of that lighter wood with that interior, so that is why I was thinking the Light Poplar might go well.
