Maya Blue is the most unique pre-Columbian pigment—a mystery that baffled scientists for decades. Maya people heated palygorskite clay with indigo, creating an extraordinarily stable blue that resists acid rain, sunlight, and bio-corrosion for centuries. The secret—revealed in the 2000s with electron microscopes—indigo molecules are trapped in clay's micro-pores, forming a "molecular cage." Maya Blue was used exclusively for rain god Chaac sacrifices. At Chichen Itza's Sacred Cenote, archaeologists found blue-coated human remains—Maya painted victims blue before casting them into the well during droughts.
