Blue gods aren't unique to India: Egyptian Amun, Thoth, and Aztec Quetzalcoatl were all depicted blue. Vedic hymns reference blue deities going back 4,000 years, though visual depictions only became possible around the 1st century AD when indigo dye appeared. Three shades carry meaning: cosmic shyama for Vishnu and Krishna, nila for Indra, and destructive shyama for Kali and demons. One theory: methemoglobinemia, a condition tinting skin blue at 15% levels, may have inspired these depictions.
