If you are getting the Vol1 Generations 2014 book, or can look at someone else's, they show the 8 or 9 colour versions in there... I just can't recall, or easily access my copy at the moment.
If the FJ comes in red, I would imagine that there is a red version of the toy... as the limited edition versions of that toy were all colours done to match the corresponding car being purchased (so that the owner had a Transformer that turned into the exact car they just purchased).
