ONE THAT COMES IN A PACKAGING THAT IS INNOVATIVE, ELEGANT, HANDY AND FEELS RIGHT.
A warm forest green with a muted undertone. The colour was popular with landscape painters during the 19th century until the end of the 20th century when ASTM testing proved the colour fugitive. Subsequently, permanent various modern mixtures have been developed to match the Hooker's Green shade.
While certain artists prefer to mix their own Hooker’s green “Phthalo Blue with Aureolin or Yellow Oxide” while earthier greens, some uses “Phthalo Blue with Yellow Oxide or Raw Sienna; however, most prefer the more accurate mix available in the tube.
They keep clean greens that you are likely to see in nature or darken other greens. It is always better to use a related but darker colour rather than black, dull the colour. However, both camps are very pleased that the colour they so loved continues to be the colourist’s favourite.
COMPOSITION AND PERMANENCE
Pigment Combination: PBk7-Lamp Black; PY14-Diarylide Yellow 14; PG7-Phthalo Green
1 PIGMENT NAME: PBK7-LAMP BLACK
Pigment Type: Inorganic
Chemical Name: Carbon
Properties
Lampblack is a very opaque, heavily staining black pigment that does not have much covering or tinting power. It is typically the opaquest black in watercolour form. Though a very pure black, it tends to muddy slightly in mixtures. Natural sources may be brownish or bluish in tone because of impurities. When used in oil paints, it is one of the slowest drying pigments and should not be used in underpainting or applied in layers underneath other colours.
Permanence
Lamp Black is very lightfast and permanent. It is used in all techniques in permanent painting.
Toxicity
Carbon itself is not considered hazardous however other combustion products that are hazardous are often present as impurities when Lamp Black is produced from natural materials. For this reason, commercial preparations of the pigment should be considered.
History
Lamp Black is a carbon-based black traditionally produced by collecting soot (known as lampblack) from oil lamps. It has been used as a pigment since prehistoric times. It is the black found in Egyptian murals and tomb decorations and was the most popular black for fresco painting until the development of Mars Black.
2 Pigment Name: PY14-Diarylide Yellow 14
Pigment Type: Organic, disazo
Properties
Pigment PY14 offers a bright yellow.
Permanence
Pigment PY14 has been reported to fade with exposure to the sun.
Toxicityandnbsp;andnbsp;n/a
History
The diarylide yellows are a family of bright yellow pigments with a similar molecular structure. Discovered by Griesheim-Elektron, Pigment Yellow 14 has been used in lithographic and offset printing applications, textiles, plastics, and paints.
3 Pigment Name: PG7-Phthalo Green
Pigment Type: Organic
Chemical Name: Polychlorinated copper (II) phthalocyanine
Properties
Phthalo Green is a transparent, cool, bright, high-intensity colour used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most hydrogen atoms have been replaced with chlorine, forming highly stable molecules. It has similar pigment properties and permanence to Phthalo Blue. It is slow drying and excellent base colour for mixing a range of bright greens. Phthalo Green is considered an excellent alternative to Viridian because it is intense and mixes well, and can be used to emphasize mineral colours in various tints. However, its tinting strength is very high to overpower other colours. This pigment most closely resembles the discontinued and toxic Verdigris.
Permanence
Phthalo Greens are completely lightfast and resistant to alkali, acids, solvents, heat, and ultraviolet radiation. Due to their stability, they are currently used in inks, coatings, and many plastics and are considered a standard pigment in printing ink and the packaging industry.
Toxicity
Phthalo Green has no significant hazards, but it contained PCBs (polychlorinated biphenyls) until 1982.
History
This bright blue-green was developed in 1935 and has been in use since 1938.
