We'll be experimenting with rust, soot and chalk in our current projects. I've looked into growing turmeric as a perennial before but found our climate to be much too cold. If we could grow it as an annual it might be worth looking into as a pigment.
Does anyone use other plant based dyes for coloring plaster or paint? We have lots of pokeberry growing on the mountain and I have been reading about fermenting the berries for fade resistant brown colored ink. Has anyone tried this as a plaster pigment, or should we experiment next fall and reply with the results?
