Color Swatch created using heavy to light application and was applied on 100 lb (163 gsm) drawing paper material.
This color contains the following pigments:
PR202—Quinacridone Magenta
Pigment Type
organic, dichloroquinacridone
Chemical Name
n/a
Chemical Formula
n/a
Properties
PR202 has a bluish red color, but is more yellow than Quinacridone Red (PR122), which is the modern favorite for Magenta in CMYK (four color) process printing.
Permanence
Although it is not the most famous magenta in the quinacridone family of pigments, PR202 belongs to a related class chemically, and is thus relatively stable and permanent for a bluish red pigment. It is one of the pigments often used in inks and toners for process printing.
Toxicity
Quinacridone Magenta has no 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
PR202 has been widely used as an automotive paint. Other applications include packaging, printing inks, and textiles.
Alternate Names
Quinacridone Fuchsia. Monastral Magenta, Fastogen Super Magenta
PV15—Ultramarine Violet
Pigment Type
inorganic
Chemical Name
complex silicate of sodium and aluminum with sulfur
Chemical Formula
H2Na(4-6)Al6Si6O24S2
Properties
Ultramarine Violet is a semi-transparent, dull purple to pale violet with low tinting strength. As a pigment, it is weak in most oil applications, but it performs better in water-based mediums, pastels, and chalks. It is generally the bluest of the violet pigments, although there can be significant differences in color across brands. It is not suitable for fresco work and does not mix well with yellows. Ultramarine Violet is a variant of Ultramarine Blue, and their pigment properties are identical.
Permanence
Ultramarine Violet has excellent permanence and lightfastness.
Toxicity
Ultramarine Violet has no significant hazards.
History
Unknown.
Alternate Names
Mineral Violet, Violet Ultramarine, Ultramarine Red.
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.
