Body paint, tattoos, and scarification were all used in different ways by the Mayan to signify important events in one's life, as well as to symbolize differing class distinctions. As evidence of skin modification from human remains can not be studied, the evidence for tattooing, scarification, and body paint among the Maya comes from iconographic images such as pottery and murals, artifacts such as tools and vessels used for storing pigment, as well as ethnohistoric accounts. Body paint patterns were incredibly localized and color and design varied according to location. Two of the most widely used colors among the Maya were red, which was made of cinnabar or vermilion, with hematite and iron ore added. Another popular culture, and one that was possibly the most valued among the Mayans was a blue or green pigment made with indigo and a mineral called Palygorskite. This blue/green color was highly valued because it was associated not only with jade, but with sacrifice to the gods as well. Spanish explorer Diego de Landa states in one of his accounts:  "...they had the custom of painting their faces and bodies red... they thought it very pleasing...the victim...having smeared him with blue... they brought him up to the round alter..." The evidence for body painting among the Mayan largely comes from various murals. One mural found in Bonampak, Chiapa shows a man being painted red from the neck down by a servant while a woman's face is painted red. Another mural found at Calakmul depicts merchants and non-elites wearing face paint of various colors and designs, suggesting that paint may have been used to differentiate class and gender. While there is a physical difference between scarification and tattoos, the Mayans may not have differentiated between the two practices. Tattoos and scarification were used to mark significant events in a Mayan's life. Diego de Landa says: "A thief from the highest class is punished by having his face tattooed on both sides from the beard to the forehead. … the young men do not tattoo except to a slight degree until marriage.”Scholar Cara Tremain argues that some tattoos and scars may have been associated with the elite, as “killing” and “rebirth” of the skin through cutting creates an association with death and the rebirth of deities. Tremain also argues that some types of tattooing and scarification symbolized valor and bravery.
