Properties

Raw Umber is a cool, transparent brown ranging from yellowish-brown to greenish-brown. It has surprisingly good tinting strength and a high opacity level, mixes well with greens, and quickly dries in oil form. It has excellent colour properties and can create a variety of subtle, clear tints when combined with white. It grays when mixed with blue and white. Raw Umber can tend towards chalkiness in dark mixes in oil form.

Permanence

Toxicity

Raw Umber itself is considered non-toxic. If contaminated by manganese compounds, it may be highly toxic if inhaled and moderately toxic if ingested.

History

This pigment comes from the Latin word umbra, meaning shadow or shade. Its full name is listed as terra dombra, meaning earth of shadow/shade, due to its original extraction from the area of Umbria, Italy. It has been used as a pigment since prehistoric times. Currently, the finest umber comes from Cyprus.
