PBr23-Van Dyke Brown
PG7-Phthalo Green
PY150-Nickel Azo Yellow
PBr23-Van Dyke Brown
organic, disazo
This organic pigment has been called Van Dyke Brown because it is so similar to the brown used by Flemish painter Anthony van Dyck, although it is in fact a modern synthetic pigment. In addition to its use in art, it has been used as a pigment for coloring plastics and synthetic fibers.
PG7-Phthalo Green
organic
polychlorinated copper(II) phthalocyanine
C32H3Cl13CuN8 to C32HCl15CuN8 or C32H16CuN8Cl15 (PG7) or C32Br6Cl10CuN8 (PG36)
Phthalo Green is a transparent, cool, bright, high intensity color used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the 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 an excellent base color for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense and mixes well and can be used to emphasize mineral colors in various tints. However, its tinting strength is very high, so it can overpower other colors. This pigment most closely resembles the discontinued and toxic Verdigris.
Phthalo Greens are completely lightfast and resistant to alkali, acids, solvents, heat, and ultraviolet radiation. 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.
Phthalo Green has no significant hazards, but it contained PCBs (polychlorinated biphenyls) until 1982.
This bright blue-green was developed in 1935 and has been in use since 1938.
PY150-Nickel Azo Yellow
inorganic
nickel azomethine yellow
C30H18Cl2N6NiO4
Nickel Azo Yellow is a transparent, moderately staining yellow pigment with high tinting strength. It is considered a good color match in botanical and landscape painting for natural gamboge (NY24), a historic yellow pigment with fair to poor lightfastness.
Nickel azomethine yellow has excellent lightfastness.
Nickel azo yellow pigment is mildly toxic, and is often labeled as hazardous. Avoid respiratory and skin exposure to pigment dust. It should be disposed of properly with other hazardous wastes, not washed down the sink.
Nickel azomethine yellow has been developed as an artist pigment becasue it is a close match for gamboge, a historic yellow.
