Umber is a natural earth pigment consisting of iron oxide and manganese oxide; it has a brownish color that can vary among shades of yellow, red, and green. [ 3 ] : 39 Umber is considered one of the oldest pigments known to humans, first seen in Ajanta Caves in 200 BC – 600 AD.
Ochre is a family of earth pigments, which includes yellow ochre, red ochre, purple ochre, sienna, and umber. The major ingredient of all the ochres is iron(III) oxide-hydroxide, known as limonite, which gives them a yellow colour. A range of other minerals may also be included in the mixture: [6]: 134 Yellow ochre (Goldochre) pigment
Raw umber (PBr7): a natural clay pigment consisting of iron oxide, manganese oxide and aluminum oxide: Fe 2 O 3 + MnO 2 + n H 2 O + SiO 2 + Al 2 O 3. When calcined (heated) it is referred to as burnt umber and has more intense colors. Raw sienna (PBr7): a naturally occurring yellow-brown pigment from limonite clay. Used in art since prehistoric ...

Mummy brown, also known as Egyptian brown or Caput Mortuum, [1]: 254 [2] was a rich brown bituminous pigment with good transparency, sitting between burnt umber and raw umber in tint. [3] The pigment was made from the flesh of mummies mixed with white pitch and myrrh.
Raw sienna and burnt sienna came from Siena, Italy, while raw umber and burnt umber came from Umbria. These pigments were among the easiest to synthesize, and chemists created modern colors based on the originals. These were more consistent than colors mined from the original ore bodies, but the place names remained.
After mining, the mineral used for making a pigment is ground to a very fine powder (if not already in the form of clay), washed to remove water-soluble components, dried, and ground again to powder. For some pigments, notably sienna and umber, the color can be deepened by heating ( calcination ) in a process known as "burning", although it ...
