IMO, Toffee is much more subdued than Truffle. I always felt Truffle was a weird colour (a good weird) and hard to describe. I think Tea pulls more red if that makes sense, like it almost has a rust-like quality.
I've seen side by side pics somewhere, lemme see if I can find them.
EDIT: I found them but it was side by sides with Steel. I have a Toffee wallet and I'll be in your 'hood next week (Wed-Fri) so if you want to meet up, I'm happy to show it to you, or you can take it home and compare to your Truffle. My wallet has developed a patina though, so the colour has darkened a bit since it was new.
