Sennelier Watercolour S3 Chinese Orange (645)

Chinese Orange (645) Nickel Azo Yellow is a transparent, moderately staining yellow pigment with high tinting strength. It is considered a good colour match in botanical and landscape painting for natural gamboge (NY24), a historic yellow pigment with fair to poor lightfastness.

Quinacridone Red is a bright, clean red pigment. Quinacridone pigments have relatively low tinting strength in general.

Van Dyke Brown because it is so similar to the brown used by Flemish painter Anthony van Dyck, although it is a modern synthetic pigment.

Pigment Name: PY150—Nickel Azo Yellow

PY150—Nickel Azo Yellow is a transparent, moderately staining yellow pigment with high tinting strength. It is considered a good colour match in botanical and landscape painting for natural gamboge (NY24), a historic yellow pigment with fair to poor lightfastness. Chemical Name: Nickel azomethine yellow

Permanence: Nickel azomethine yellow has excellent lightfastness.

Toxicity: Nickel azo yellow pigment is mildly toxic and often labelled hazardous. Avoid respiratory and skin exposure to pigment dust. It should be disposed of properly with other hazardous wastes, not washed down the sink. However, the contribution of artist pigments to levels of nickel metal complexes in the environment is almost insignificant. Nickel is often present in the environment naturally. Nickel is used heavily in steelmaking and many industrial processes and products.

History: Nickel azomethine yellow has been developed as an artist's pigment because it is closely matched to gamboge, a historic yellow.

Alternate Names: Gamboge Hue, New Gamboge.

Pigment Name: PR209—Quinacridone Red

PR209—Quinacridone Red is a bright, clean red pigment with an average drying time. Quinacridone pigments have relatively low tinting strength in general. For this reason, quinacridone colours are often expensive because more pigment is required in the formulation.

Permanence: Quinacridone Red has excellent permanence and lightfastness.

Toxicity: Quinacridone Red has no known acute hazards. However, overexposure to quinacridone pigments may cause skin irritation. Quinacridone pigments contain a compound that is a skin, eye, and respiratory irritant.

History: Although quinacridone compounds became known in the late 19th century, manufacturing methods to make them practical for use as commercial pigments began in the 1950s. Quinacridone pigments were first developed as coatings for the automotive industry but were quickly adopted by artists.
