Natural colours

The colours that the ancients used to decorate their magnificent temples could be plant, animal or mineral in origin.
Minerals called haematite and cinnabar, or ox blood, were used to produce red.
Yellow was extracted from another mineral called limonite, blue from azurite, and green from malachite.
White, on the other hand, was extracted from white lead, while some colours such as brown involved burning plants with animal bones.
