Pigment information

Dioxazine Violet

Pigment code: PV23
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.
History: Two molecular variants of Dioxazine Violet, PV23 and PV37, are available. They have similar properties, but mix slightly differently.
Description: Dioxazine Purple, Chromothal Violet, Mauve, Carbazole Violet.

Phthalo Blue

Pigment code: PB15:3
Type: organic
Chemical name: beta copper phthalocyanine
Chemical formula: C32H16CuN8
Properties: Phthalo Blue PB15:3 is a structural variant of Phthalo Blue PB15 that produces more greenish tones.
Permanence: Phthalo Blues are completely lightfast and stable and are permanent for all paint uses. They are currently used in inks, coatings, and many plastics due to their stability and are considered a standard pigment in printing ink and the packaging industry.
Toxicity: Phthalo Blues have no significant hazards, although those made before 1982 contained some PCBs (polychlorinated biphenyls).
History: Developed by chemists using the trade name Monastral Blue, the organic blue dyestuff now known as Phthalo Blue was presented as a pigment in November 1935 in London. Its discovery was accidental. The dark color was observed in a kettle where a dye was being made from a British dyestuff plant. The demand for such a pigment came from commercial printers who wanted a cyan to replace Prussian Blue.

Lamp Black

Pigment code: PBk6
Type: inorganic
Chemical name: carbon
Chemical formula: C
Properties: Lamp black is a very opaque, heavily staining black pigment that does not have much covering power. It is typically the most opaque black in watercolor form. Though a very pure black, it tends to muddy slightly in mixtures, is one of the slowest drying pigments in oils, and should not be used under other colors.
Permanence: Lamp Black is very lightfast and absolutely permanent. It is used in all techniques in permanent painting.
Toxicity: Lamp Black is slightly toxic by skin contact and inhalation. It is a possible human carcinogen.
History: Lamp Black is a carbon based black traditionally produced by collecting soot (known as lampblack) from oil lamps. It is the black found in Egyptian murals and tomb decorations and was the most popular black for frescoing until the development of Mars Black.
Description: Carbon Black, Channel Black, Oil Black, Vegetable Black. Flame Black is an impure version of Lamp Black.
