Tupã Matis demonstrating how to process the green fruit of jenipapo (Genipa americana) from which a black dye is obtained.  The black dye is used in face and body painting.  In addition, the dye is mixed with other pigments (e.g. copal) to create an ink that is used to make permanent tattoos.  The ripe fruit of jenipapo can be used to make a fruit drink that is high in Vitamin C.
