R&F Pigment Stick - Turkey Red, 38 ml
Turkey Red comes from a laboriously produced but widely used plant dye imported from Turkey in the 18th and 19th centuries. The top tone of our Turkey Red is an earthy bluish red that breaks into a warm, earthy scarlet undertone—a mix of Quinacridone Red, Indian Yellow, and Raw Sienna.

Pigment Name: PV19 Quinacridone Violet
Classification: Synthetic Organic, Quinacridone
Chemical Composition: Quinacridone Magenta
Properties
Quinacridone Red is a high-performance, transparent pigment with an average drying time and uneven dispersal. It is another name for Quinacridone Violet (PV19) and Quinacridone Red (PR192). Quinacridone pigments generally have relatively low tinting strength. For this reason, quinacridone colours are often expensive because more pigment is required in the formulation.
Permanence
Quinacridone Violet has excellent lightfastness and is considered the most lightfast organic pigment in this shade range.
Toxicity
Quinacridone Violet has no known acute hazards. Overexposure to quinacridone pigments may cause skin irritation. Quinacridone pigments contain a compound found to be a skin, eye, and respiratory irritant.
History
Although quinacridone compounds became known in the late 19th century, manufacturing methods to make them practical for use as commercial pigments began in the 1950s. Quinacridone pigments were first developed as coatings for the automotive industry but were quickly adopted by artists.
Pigment Name: PY83 Diarylide Yellow 83
Pigment Type: Organic, disazo
Chemical Composition: Disazo pigment
Properties
Diarylide Yellow is a semi-opaque, moderately staining, intense, deep reddish yellow pigment with good tinting strength.
Permanence
Diarylide Yellow 83 has excellent lightfastness and permanence. However, it can fade in tints, so some artists do not consider it suitable as an artist’s colour. Many other diarylide yellow pigments are reported to have fair to poor lightfastness, and some are entirely fugitive. Diarylide Yellow 83 is one of the most permanent of the entire group.
Toxicity
Diarylide Yellow has no significant acute hazards, but chronic hazards have not been well studied.
History
Diarylide Yellow comes from a family of azo pigments called Diarylide. These yellow-hued pigments were developed around 1940 and are essential in printing inks.
Pigment Name: PBr7 Raw Sienna
Classification: Earth
Chemical Composition: Hydrated iron oxide
Properties
Raw Sienna is a moderately dull deep earth yellow with medium tinting strength and excellent transparency. It is one of the essential permanent artists' pigments and is made from a form of limonite clay whose yellow-brown colour results from ferric oxides. Raw Sienna is preferable to Yellow Ochre for creating flesh tones due to its higher subtlety of colour when mixed with white. It makes a bright Ochre when mixed with Cadmium Yellow and creates greens and grays when mixed with Ultramarine. Raw Sienna dries quickly.
Permanence
Raw Sienna has good permanence.
Toxicity
Raw Sienna has no significant hazards.
History
Raw Sienna has been a pigment since prehistoric times, although its current name originated during the Renaissance. It comes from Siena in Italy and is short for terra di Siena, meaning the earth of Siena. Sienna was famous for mining and producing earth pigments from the Renaissance until World War II. Due to the depletion of clay deposits in Tuscany, Italian sienna now comes from other areas, including Sicily and Sardinia.
