This color contains the following pigments:
PR209—Quinacridone Red
Pigment Type
organic, quinacridone
Chemical Name
n/a
Chemical Formula
n/a
Properties
Quinacridone Red is a bright, clean red pigment with average drying time. 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 Red has excellent permanence and lightfastness.
Toxicity
Quinacridone Red has no known acute hazards. Overexposure to quinacridone pigments may cause skin irritation. Quinicridone pigments contain a compound found to be a skin, eye, and respiratory irritant.
History
Although quinacridone compounds became known in the late 19th century, methods of manufacturing so as to make them practical for use as commercial pigments did not begin until the 1950s. Quinacridone pigments were first developed as coatings for the automotive industry, but were quickly adopted by artists.

PR264—Pyrrole Rubine
Pigment Type
organic, aminoanthroquinone
Chemical Name
1,4-diketo-3,6-di(4'-tertiary butyl phenyl)-2,5-dihydro pyrrolo[3,4-c]pyrrole
Chemical Formula
n/a
Properties
This bluish red transparent pigment has high tinting strength. Diketo pyrrolo pyrrole pigments are noteworthy for their light stability, excellent weatherability, and outstanding heat stability.
Permanence
Pyrrole Rubine has excellent permanence and lightfastness for an organic pigment in its color range.
Toxicity
Pyrrole pigments are considered to be non-toxic.
History
The Pyrrole group of synthetic organic pigments was developed in the 1980s. Pyrrole Rubine was first manufactured by Ciba Specialty Chemicals under the trade name Irgazine Ruby. Although not a perfect match for alizarin crimson, Pyrrole Rubine is one of several new pigments that has helped to close a traditional gap in the gamut of artist pigments, the lack of lightfast and transparent colors in the red/blue and red/violet parts of the spectrum.
