Prehistoric cave murals, dating back to the Upper Paleolithic period, were created using a variety of natural pigments and specialized techniques.

Pigments

Artists primarily utilized red and black pigments to create their imagery.1
* Red: Derived from iron oxides, specifically hematite.1
* Black: Sourced from manganese dioxide and charcoal.1
* Other shades: Some sites, such as Lascaux, also feature paintings in various shades of brown and yellow.2

Tools and Techniques

The creation of these murals involved both additive and subtractive methods:
* Engraving: Artists used their fingers to draw on soft surfaces or employed flint tools to carve into harder rock walls.1
* Painting: Images were often executed in combination with engravings, such as at Altamira, where figures were first carved and then painted.2
* Access and Perspective: To reach high walls and ceilings, creators utilized scaffolding. Additionally, they often incorporated the natural contours of the rock surface to provide a three-dimensional quality to their work.2
