What colour is the skin of a chimpanzee?

It starts out pink in babies and turns dark at adulthood. Look up the St. Louis zoo and see if you can find a picture of cinder. Cinder is an adult chimp with no hair. Cinder is grey. I looked but I could not find a picture of her. She has a condition which caused her body to stop growing hair. Other than that cinder is fine. I have seen her several times in the last few years asI take my science students to the zoo once a year.|||Look at a chimps face it has no hair there thats the color its skin is.
