In tomb paintings, men were always shown with brown faces, women with yellow ochre or gold faces.
Opal is a hydrated amorphous form of silica (SiO 2 · n H 2 O); its water content may range from 3% to 21% by weight, but is usually between 6% and 10%. Due to its amorphous property, it is classified as a mineraloid, unlike crystalline forms of silica, which are considered minerals. It is deposited at a relatively low temperature and may occur ...
Glauconite is an iron potassium phyllosilicate ( mica group) mineral of characteristic green color which is very friable [ 5] and has very low weathering resistance. It crystallizes with a monoclinic geometry. Its name is derived from the Greek glaucos ( γλαυκός) meaning 'bluish green', referring to the common blue-green color of the ...

The addition of an oil binder helped to make the paint permanent and waterproof. Orange and red paint contained hematite or iron oxide, while yellow came from limonite, blue and green from copper or serpentine, white from kaolin clays or gypsum, and black from manganese or charcoal. Paint was applied with a person's finger or a brush.
