Language Proto-Germanic
First Recorded Use Prehistoric

History

Red pigments have been among the first and most widely used colors by humans. Early reds were derived from natural minerals like hematite (red ochre), cinnabar, and later from organic sources like madder root and cochineal insects. The use of red ochre in prehistoric cave art (e.g., Lascaux, Altamira) is well-documented. Ancient Egyptians used red for cosmetics and tomb paintings. Romans valued cinnabar for frescoes. In medieval Europe, madder and kermes were important for textiles. The discovery of cochineal in the Americas revolutionized red dyes and pigments. Synthetic red pigments began to emerge in the 19th and 20th centuries, offering greater stability and variety.

First Recorded Use

Evidence of red pigments (ochre) used in cave paintings dates back tens of thousands of years.
