What materials do pigments in ancient paintings come from?

More than 200 years BC, the painting colors on the mural fragments in Qin and Han dynasties have been red, vermilion, black, brown, azurite and stone green. Cinnabar, red lead, carbon black and lead white were also used in the painting pigments of the Terracotta Warriors and Horses of Qin Shihuang.

After Wei and Jin Dynasties, the color varieties of Chinese painting pigments became more and more abundant, especially Dunhuang art. According to research and analysis, the pigments used in Dunhuang murals are cinnabar, red soil, realgar, red lead, iron red, rouge, cinnabar, and the green ones are stone green (malachite).
