Raw Umber is a cool, transparent brown ranging from yellowish brown to greenish brown. It has surprisingly good tinting strength, a high level of opacity, mixes well with greens, and is quick drying in oil form. It has excellent color properties and can create a variety of subtle, clear tints when mixed with white. It grays when mixed with blue and white. Raw Umber can tend towards chalkiness in dark mixes in oil form.
Raw Umber has excellent permanence.
Raw Umber itself is considered non-toxic. If contaminated by manganese compounds, it may be highly toxic if inhaled and moderately toxic if ingested.
This pigment gets its name from the Latin word umbra, meaning shadow or shade. Its full name is listed as terra di ombra, 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.
Chestnut Brown, Euchrome, Jacaranta Brown, Mars Brown, Raw Brown, Sicilian Brown. Cyprus Umber, Turkey Brown, and Turkey Umber are the best quality umbers.
Asphaltum is a transparent black pigment with low tinting strength. It is often used as a glazing black.
In high concentrations it interferes with drying and bleeds into other colors. It is prone to decomposition when exposed to sunlight.
Asphaltum is non-toxic and non-carcinogenic.
Asphaltum is a natural hydrocarbon mineral. Although it is found in mineral deposits, it is more often produced synthetically as a residue from petroleum processing or as a distillate from coal gases. Naturally occurring deposits of asphaltum have been used since prehistoric times for waterproofing. It has been used as a pigment since at least the 16th century, and probably much earlier.
