Developed in Nuremberg in 1868 — the same year that synthetic alizarin destroyed the madder industry — manganese violet was the first true violet pigment. Before it, artists had to mix blue and red to approximate violet, always resulting in either a blue-purple or a red-purple rather than a true spectral violet.

Rare, precise, and slightly medicinal. Manganese violet sits at the exact midpoint of purple — neither warm nor cool, neither blue nor red. This neutrality makes it both useful and slightly characterless on its own. It is the professional's violet — not romantic or theatrical, but precisely placed.

Manganese violet's development in 1868 represented the first time artists could achieve a true spectral violet without mixing — previously impossible. The Impressionists, who were deeply interested in spectral colour relationships, adopted it enthusiastically as part of their systematic approach to colour.
