The yellow is colour of the friendship
However, tell the true, the Yellow Baboons are "hard guys", serious "warriors"... The Yellow Baboon (Papio cynocephalus) is a baboon in the family of Old World Monkeys. The species epithet literally means "dog-head" in Greek, due to the shape of its muzzle and head. It has a slim body with long arms and legs and a yellowish-brown hair. The Yellow Baboon inhabits savannas and light forests in the eastern Africa, from Kenya, Tanzania to Zimbabwe and Botswana.
