Since the 19th century, the common way to dye indigo (blue) is by using chemic colour – and so, we assume, there is no natural blue. But where there is not yet any cars or electricity, they still know the secret.
On my trip in the Dogon Country, in the village Ennde, I visited a family that dye indigo-cloth. Keeping the dogon tradition, they sew patterns in the (often handwoven) cotton-fabrics before it is dyed, creating undyed spots – kind of like the once-so-popular tie-die.
The colour Indigo comes from the indigo-flower – but I couldnt see any cause they only grow in the rain season. The dyers dry the flowers and clump them together for storage, luckally, they had one spare for me to bring home!
Obtaining the clear blue from Indigo is not so easy (as other colours), and thats where the sugarlike substance on the left comes into play..
As my translator did not seem to be an indigo-expert himself, he told me it is harpix for fixing the colour – after reading about indigo on wikipedia however, it seems it must be a sulfate/acid, for avoiding the immediate oxidation of the indigo after the dyeing. I was carefully explained not to touch it, and to pack it in many layers of plastic. (But they still use their bare hands for dyeing..)
Well, I had some difficulties understanding this part, but it seems it is made from burned “miel” – a wonderplant that is used for everything here; bread, to, tread, ryes, hay, beer…
After it is burned; it gets steam-boiled …and somewhere in this process it turns acid…
-well, I guess I’m not donna do this part at home.
After all theese preparations the dyeing itself seems simple; sulfate/acid and fine grained indigo are being boiled in water, and the fabrics are then added, staying only short in the water for a light colour and longer for the typical dark indigo.
As I get home, I’ll definately check it out!!

..and.. here’s a photo of me in the cliffs of Dogon (Bandiagara Escarpment), overlooking Ennde, with my new indigo head-scarf… :)
update 1: it hit me, that it might not be very environment-friendly to use strong acids in the colouring process, particulary not sulfate… does someone know something about this, or any other options??
