Ancient blue techniques from India to Nigeria

Artisans across the globe spent millennia turning living plant extracts into rich shades of blue, but the real genius was how they controlled the resist. Yoruba makers in southwestern Nigeria painted cassava starch or hand-tied cotton to shield specific areas from the vat. Halfway across the world, Indian craftspeople stamped carved wooden blocks loaded with mud paste to block the color with absolute geometric control.

Separated by oceans and materials, both traditions transformed a simple chemical reaction into a universal canvas for local graphic identity.

Is modern digital print actually making progress, or are we just using faster technology to chase the depth these makers achieved with mud, starch, and raw chemistry?
