Pigment Type

Properties

Yellow Ochre provides artists with earth tones from cream to brown. It has good hiding power, produces quick-drying paint, and can safely mix with other pigments. Its transparency varies widely from opaque shades to more transparent ones, which are valued for their use as glazes.

If gypsum is present, Yellow Ochre is not suitable for frescoing. (See Brown Ochre, PY43.) PY42 is made from synthetic iron oxides. PY43 is made from natural iron oxide.

Permanence

Yellow Ochre has excellent permanence because ochres are some of the most permanent pigments available.

Toxicity

Yellow Ochre is non-toxic unless it contains manganese.

History

Ochre comes from the Greek word ochros, meaning pale yellow. It was one of the first pigments used by human beings, and evidence of its use has been found at 300,000-year-old sites in France and former Czechoslovakia.
