Ochre and the earth pigments [edit]. 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 color.odern ochre pigments often are made using synthetic iron oxide. Pigments which use natural ochre pigments indicate it with the name PY-43 (Pigment yellow 43) on the label, following the Colour Index International system. Limonite, a mineraloid containing iron hydroxide, is the main ingredient of all the ochre pigments.
Ochre's primary use prehistorically was as pigments--coloration for everything from rock art paintings to pottery to human tattoos. It is the earliest pigment used by humans to paint our world--perhaps as long ago as 300,000 years.chre is very common on archaeological sites world-wide, and it is generally assumed to be a coloring agent. The earliest possible use of ochre is nearly 300,000 years old, in the site of GnJh-03 in the Kapthurin Formation of East Africa, and at Twin Rivers in Zambia.
