>>9257654>>9258210I knew the coloration look familiar! A color scheme or few I'd like to see would be the T-Rex from Jurassic Park, as well as Beast War's Megatron purple coloration.
As for camouflage, consider the patterns used by modern day apex predators (lions, tigers, bears, crocodiles, etc.), their hunting techniques, and where they live. Now, I'm not expert on this sort of thing, but if a Tyrannosaur lived in a heavily wooded area, I'd say it would probably use a bunch of browns and other earthy tones for its main color, matching the wood and help blend into the foliage.
Little off-topic: has there been a consensus on how a Tyrannosaur vocalized? I've seen videos and the like that show it growling like a crocodile, using a deep, bass rumble, or vocalizing like a giant bird.
