Q0751Ultramarine blue, ground from lapis lazuli, was once so costly that artists used it deliberately for the most precious parts of a painting.
Before synthetic pigments, deep ultramarine depended on rare lapis lazuli and long trade routes. Its cost meant blue could signal status, devotion and patron wealth, not just colour preference. This matters globally because materials shape style as much as imagination does. The lesson: beauty often has a supply chain.
