Feathers I can accept, if and when there is evidence that T-Rex was also sporting feathers. Considering, however, that the total number of complete T-Rex skeletons discovered ever is, I think, six, the likelihood of finding a new one to be studied with the newest available technology and archeological data is quite small.
It is, however, the color scheme that strikes me as somewhat off... as a top predator, a T-Rex would have likely had coloration that allows it to blend into its surroundings while stalking its prey. This would have been of crucial importance considering that T-Rex likely wasn't too fast a runner, so getting close to its prey unnoticed would have been imperative. Some scholars actually suggest that the T-Rex hunted the same way as the modern Komodo dragon: that its mouth was so filled with bacteria (and in case of the dragon, poison) that one bite would effectively cause sepsis and kill the bitten prey in a few days.
This, however, is just me rambling from a Walking With Dinosaurs and childhood enthusiasm of dinosaurs -level of knowledge, so I could be way off.
