Brachiosaurus the gentle giant

I see Brachiosaurus as a peaceful creature. It was so big that it didn't need to have any form of defence other than size and its tail. They were probably a dull colour in my opinion.

Is there a possibility they were colorful?

Okay, A. Brachiosaurus had to watch out for Allosaurus, Saurophaganax, A. amplexus or whatever the dinosaur is, and Torvosaurus. It is nowhere near safe. B. I think it was peaceful, but not defenseless. Just look at an Elephant, normaly peaceful, but can be a vicious fighter. C. I think it was warm blooded. Its tall neck was like a Giraffe's neck on steroids. D. I think it had pretty dull colors. Browns, dark greens, a bit like the forest.

I see Brachiosaurus as being peaceful most of the time, but like any animal, if threatened, could be aggressive. And let me tell you, when 50+ tons of muscle fights back, watch out! I see perhaps a splash of colors on the male's head, kinda like JP III [img]http://images4.wikia.nocookie.net/__cb20120831151703/jurassicpark/images/e/e5/Jurassic_park_3_brachiosaurus.jpg[/img] Like most, if not all, dinosaurs, Brachiosaurus was probably warm-blooded.
