It is likely the pigment got the name from the uniform. Additionally the pigment would have not been used as a dye, because it would have been expensive. Woad was the likely dye – it was a cash crop and the Prussian military’s demand for blue uniforms was a means of supporting the peasantry that harvested the crop. Later, Indigo probably supplanted Woad as the dye.
