Sennelier Watercolour S1 Phthalo Green Light (805)

Phthalo Green Light (805) Nickel dioxine yellow is a semi-transparent, lightly staining yellow pigment with high tinting strength, although less than the diarylides. It is considered a good colour match for Indian Yellow, a historic pigment that is no longer available. Drying time is average.

Phthalo Green is a transparent, cool, bright, high-intensity colour. It is an excellent base colour for mixing a range of bright greens. Phthalo Green is considered a good alternative to Viridian because it is intense, mixes well, and can be used to emphasize mineral colours in various tints.

Pigment Name: PG7—Phthalo Green

Phthalo Green is a transparent, cool, bright, high-intensity colour used in oil and acrylics. It comes from a Phthalocyanine Blue pigment in which most hydrogen atoms have been replaced with chlorine, forming highly stable molecules. It has pigment properties and permanence similar to Phenthalo Blue. It is slow-drying and an excellent base colour for mixing a range of bright greens.

Phthalo Green is considered a good alternative to Viridian because it is intense, mixes well, and can be used to emphasize mineral colours in various tints. However, its tinting strength is very high, so that it can overpower other colours. This pigment most closely resembles the discontinued and toxic Verdigris. Chemical Name: polychlorinated copper(II) phthalocyanine

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 used since 1938.

Alternate Names: Bocour Green, Cyan Green, Intense Green, Monastral Green, Phthalocyanine Green, Rembrandt Green, Thalo Green, Winsor Green.
