Color Swatch created using heavy application/medium application/50% tint and was applied on acrylic primed canvas (7 oz) material.
This color contains the following pigments:
PR206—Quinacridone Pyrrolidine Red
Pigment Type
organic, quinacridone
Chemical Name
quinacridone pyrrolidine
Chemical Formula
n/a
Properties
PR206 offers a deep maroon or bordeaux red. Quinacridone pigments have relatively low tinting strength in general. For this reason, quinacridone colors are often expensive, because more pigment is required in the formulation.
Permanence
Quinacridone pigments have excellent lightfastness.
Toxicity
Quinacridone Pyrrolidine Red has no known acute hazards. Overexposure to quinacridone pigments may cause skin irritation. Quinicridone pigments contain a compound found to be a skin, eye, and respiratory irritant.
History
It was developed as a maroon or bordeaux red for automotive paints.
Alternate Names
Monastral Maroon
PV19—Quinacridone Violet
Pigment Type
organic synthetic, quinacridone
Chemical Name
n/a
Chemical Formula
C20H12N2O2
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 have relatively low tinting strength in general. For this reason, quinacridone colors 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. Quinicridone pigments contain a compound found to be a skin, eye, and respiratory irritant.
History
Although quinacridone compounds became known in the late 19th century, methods of manufacturing so as to make them practical for use as commercial pigments did not begin until the 1950s. Quinacridone pigments were first developed as coatings for the automotive industry, but were quickly adopted by artists.
Alternate Names
Quinacridone Red (PR192), Quinacridone Red (PR19).
PV23—Dioxazine Violet
Pigment Type
organic
Chemical Name
carbazole dioxazine
Chemical Formula
C34H22Cl2N4O2
Properties
Dioxazine Violet is transparent and has very high tinting strength. It is a staining pigment, very dark valued when it is used at full strength. Concentrated, it paints out nearly black, but it mixes with Titanium White to form bright, opaque tints of purple. PV23 produces slightly redder shades than PV37. Because the hue can vary with the conditions of preparation and grinding, it may be offered in red shade, blue shade, and so forth.
Permanence
Dioxazine Violet has good lightfastness. There may be some concern about it fading or shifting in color in tints and washes. Some artists have reported that PV37, a molecular variant, is more lightfast than PV23.
Toxicity
n/a
History
Two molecular variants of Dioxazine Violet, PV23 and PV37, are available. They have similar properties, but mix slightly differently.
Alternate Names
Dioxazine Purple, Chromothal Violet, Mauve, Carbazole Violet.
