Great question! For many dinosaurs we don't know what their exact colors looked like.

Scientists can make guesses based on the information they have, but these are just guesses and not facts. So the dinosaurs you see on TV and in the movies could have been a completely different color in real life, we just don't know. However, there are a few dinosaurs that we do know exactly what they looked like!

For example, I have included a link to an article where scientists were able to tell exactly what color the dinosaur was from head to toe by looking just at its cells. Scientists are working hard to learn all they can about dinosaurs that no longer exist, but there may be some things that we will never know.
