Female body painting is a tradition associated with Xingu Indian ceremonies and rituals.  In this image, these indian girls are painting each other in preparation for the "Jogos Indigenas" (Indigenous Games) of Campo Novo, Mato Grosso, Brazil.  Each year, the native tribes of the State of Mato Grosso in Brazil compete against each other in their equivalent of the Olympic Games.  The Indigenous Games have opening ceremonies just like the Olympic Games do, and they are extremely colorful with the indigenous people demonstrating their traditional body painting.
