Abstract
It has long been obsered that certain physical and chemical processes involving sulfur-containing substances produce colors of violet, indigo-blue, blue and green, some of which are remarkable in their beauty. These color reactions are historically closely linked to hypothetical modifications of elemental sulfur; black sulfur, which is translucent blue in thin layers, Magnus's sulfur and Wöhler's blue sulfur. The presence of these modifications in ultramarine was explained by a number of scientists as the reason for its diverse colors.
