Yellow ocher is derived from natural minerals found in many locations of the earth. This is a process whereby yellow ochre turns red (red ochre, burnt ochre), the yellowish-brown pigment from Sienna changes to a clear reddish-brown (burnt sienna) and the raw yellowish umber turns to dark reddish-brown (burnt) umber. In volcanic regions this occurs naturally; however, by simply heating the pigment, the same effect is achieved.
