The largest of dinosaurs (like the giant sauropods) were probably neutral-colored or grey, like the largest animals today (eg. elephants). No one knows exactly what colors or patterns most of the dinosaurs were. One fossilized dinosaur find in 2009 included fossilized proto-feathers with microscopic cellular signs of color -- melanosomes that produce a reddish color.
Fossilized skin impressions have only been found for a small fraction of the known dinosaurs. Not much is known about dinosaur skin and there is some debate among paleontologists about this topic. Most skin fossils show bumpy skin, not scaly skin; only the huge plant-eaters seem to have had scaly skin. Some of the bird-like dinosaurs had protofeathers (a type of modified scale).
A bumpy fossilized T. rex skin imprint was found by a 12 year old.
The ankylosaurids had bony plates fused into their leathery skin, which was excellent protection from predators.

Some bird-like dinosaurs had proto-feathers. Sme of these dinosaurs include:
