Why Kano is indigo

Kano is the largest city of northern Nigeria and for centuries stood at the southern end of trade routes across the Sahara. Near one of the old city gates are the Kofar Mata dye pits, which local tradition dates to 1498. Each pit is a deep well filled with water, indigo, ash and potash, left to ferment. Dyers sit at the rim and dip cloth again and again; more dips give a darker blue. The finest cloth is then beaten with wooden mallets until it shines almost like metal. Kano cloth was once traded across West Africa and the desert. Only some of the pits are in use today, as factory cloth has taken much of the market.

Values are fair approximations of what the eye sees there, not measurements.
