Perinone Orange
PO43
Alternate Name
PO43(DL)
Pigment Description
With moderate lightfastness, best to do some research if this pigment is part of your workflow. The pigment code may be listed as PO43(DL), which connotes that it may darken in strong light.
Only one major manufacturer uses Perinone Orange as single-pigment paint in oils, however five other paintmakers have used it in a long list of blends. Lightfastness can dip to a five on the blue wool scale in some cases, so best to do one's own tests. Please take extra caution if working with its in a dust form -- consult Monona Rossol's work for more. This may be relevant to keep in mind as this pigment is sometimes used for pastels.

Stats
Lightfastness
Varies, may be Poor
Though it is listed as an ASTM in oil and acrylic, the lightfastness readings for this pigment are only moderate in some cases and it goes down from there. We find ratings of 5 and 6 on the BWS unacceptable, and it is fairly common to see a "6" in the BWS ratings for this pigment. The 1980s NPIRI notes that indoor exposures remained intact but reported “appreciable” change in both masstone and tints in outdoor lightfastness tests.
Transparency
Transparent
Toxicity
Previously thought to be in the category of Low Concern, new research suggests there is not enough data, and that the inhalation of dust may pose an "unreasonable hazard\”. Do not breathe dust
See Monona Rossol's research available upon request here for more information. Treat all pigments and paints with studio safety protocols.
Dry Time
Medium
Some paint companies indicate a short dry time (less than 2 days).
Particle Size
Fine
Chemical Name
