Is it possible, and is it safe, to dye one's entire body blue? I understand that the Tuareg's bodies are inadvertantly stained blue by the indigo-dyed clothes they wear. I want to replicate this head to toe blue effect, but not indirectly, is that possible?
I believe it is unsafe to colour ones entire body. Do not attempt to dip yourself in a dye vat.
The Tuareg are coloured by dye transfer from their outer garments, like wearing a new pair of jeans. It's unlikley that they would be eavenly coloured all over. Colouration by crocking (rubbed dye transfer) is not like a stain it is easily removed from the skin.
