6000-Year-Old Fabric in Peru Reveals Pre-Historic Use of Indigo Blue Dye

A 6000-year-old ancient fabric discovered in Peru reveals that pre-historic Peruvians have used indigo blue dye (the color we see in jeans today) long before Egyptians did. The newly discovered Peruvian textile is older than the indigo dyed fabrics in Egypt by 1,500 years and in China by 3,000 years.
