Anyone who has ever taken a look at the cave and rock paintings in Huashan on Hua Mountain (Huāshān yánhuà 花山岩畫) in China, in Altamira in Spain or, for example, in the Cueva de las Manos in Argentina, will see the many pictures painted with red, yellow and black colours (pigments). To paint these pictures, people used pigments that they found in their surroundings. These were mainly yellow ochre, red ochre or charcoal.
