The Kogi are an indigenous ethnic group that lives in the Sierra Nevada de Santa Marta in Colombia. They all wear only pure white clothing. They say that white represents the Great Mother and therefore the purity of nature. Children have long hair but the girls can be recognized because they wear a necklace. Men live in a separate hut from the women and children and they're never seen without a poporo, a gourd filled with lime and coca leaves while women rule the house and the domestic arena.
