Jurassic Park III introduced a lot of things that were never really explained. A popular explanation is that the Brachiosaurus we see in JPIII was male, seeing as how male T. rex are green and Dr. Grant mentions seeing the alpha male of a Brachiosaur herd, though the latter statement is pretty vague.

I always felt that the reason why many of the animals in JPIII were green (or greener in the case of T. rex) was because they were simply adapted to the environment, but due to a lack of official explanation, you can come up with varied explainations.
