One of the oldest pigments known, used since 8000 BCE. Derived from the mineral cinnabar (mercury sulfide), it was prized for its intense orange-red hue. Ancient Romans used it for frescoes and manuscripts. Chinese artists used it for over 2000 years. The name comes from the Latin "vermiculum" — referring to the kermes insect, though true vermillion comes from mineral cinnabar.

The most visceral of reds — stimulates urgency, danger, and raw energy. Neither as romantic as crimson nor as aggressive as pure red. Associated with fire, life force, and transformation in Eastern traditions.

Sacred in Chinese culture — used in imperial seals, lacquerware, and New Year celebrations. In Renaissance Europe, it was the most expensive pigment after ultramarine blue. Roman generals had their faces painted vermillion for triumph ceremonies.
