well, the RX 7's is in between red and orange. But right on the hood, if you stare right in front of the car, it says Orange Julius.
the Supras definitely is in gold. Or mix of gold and brown.
you can see it yourself from some of the spy pics
and Nitrous, I have to agree with you about Vin Diesel. I guess its cuz he was asking $20 million to do the sequel and Hollywood thought that was too much =/
Oh well, based on what I saw, I think part 2 no matter what will be better than the first one. Or at least, they'll have ALOT better looking cars
