Well to start they had scales or feathers, not bare skin. But also, humans have no proof of what the colors of dinosaur scales/feathers were since they decompose unlike the bones. They only have evidence of scales/feathers because of imprints in the rocks by the fossils. However, the chameleon can change colors. It does this using cells called chromatophores which contain pigment or reflect light in certain ways. They mainly change colors for display to prospective mates but it can also change according to temperature and mood. Camouflage is a more of a secondary reason.
You can't!
people don't know the color of dinosaurs. the dinosaur skin color seen in books and TV isn't 100% accurate they are just guessing

A Chamelion changes it's skin color to show how it is feeling
No one can be sure yet but I would say all sauropods (long-necked dinosaurs) had a darkish blue or purple skin colour/color when they were alive.
You can't

The only way to change skin color is through tattooing. OK, but please see discussion area.
No, dinosaurs had dry skin. Depending on the type most dinosaurs either had feathers or scales.
No one really knows what color the dinosaurs were. But due to modern analogs (Alligators and birds) we can assume that dinosaurs were green like other reptiles. But unfortunately, we will never know because it is very hard for soft-part of the body to become fossilized.
No. Your skin will in fact be healthy.
