touareg

Girls from the Tuareg tribe wearing traditional dry-dyed indigo veils.  Indigo is a plant-based, metallic dye, and is so richly beaten into the fabric that it rubs off onto their skin, turning them a deep blue-violet.  “Tuareg” means “Blue People”, and indigo is so precious that the tribespeople wear their stains with as much pomp as if their skin were shining with diamond dust.
