As for skin color, there have been very few hints to actual dinosaur colors, other than the fossilization of mummified dinosaur skin on an ankylosaur. While it didn't give an exact hue or color, it did heavily hint a spectrum of red-browns on top, with a lighter color tummy. The pigment cells, fossilized, had properties similar to modern animals with that pigment.

Raptors are small enough that their garish colors are plausible, but lizards are such a different scale than ceratopsian dinos that the colors make less sense. They should probably be more muted, perhaps with brighter displays on the shield. That does not, however, mean these designs aren't incredibly cool.
