During the Nineteenth Century there was a revolution in painting and the arts in general with the advent of synthetically manufactured colour. Blue, for instance, was no longer simply indigo. This technological advance however, pioneered by chemist Friedlieb Ferdinand Runge, and manufactured predominantly along the Rhine in Germany, later took a more sinister turn, leading, ultimately to the Nazi death camps.
