Pigment information

General reference notes about pigments can describe other media (such as oil). They do not verify this product’s exact formulation or behavior.

Phthalo Blue

Pigment code
PB15
Type
organic
Chemical name
copper phthalocyanine
Chemical formula
C32H16CuN8
Properties
Phthalo Blues are pure and clean primary blues with superior covering power. They have a very high tinting strength and tend to overwhelm other pigments, but if color strength can be controlled, they make predictable mixed colors. In oil form, blues are very deep and slow drying. When mixed with other colors or if chlorine is added, Phthalo Blue quickly tends towards green. When using alone, mix with some white, as Phthalo Blue can be semi-transparent and almost black on its own. It is among the most compatible of modern colors with mineral colors and is considered more reliable than Prussian Blue, while sharing the same physical and color properties. Phthalo Blue is a good color for glazing.
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.

Quinacridone Violet

Pigment code
PV19
Type
organic synthetic, quinacridone
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.

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.
