Quinacridone Violet B
A vital pigment to the palette, it comes in three natures-- plum, magenta, and sometimes red. Usually one sees Quinacridone Rose (magenta) and Quinacridone Violet. The Rose version is a cool, almost electric pink, sometimes called Quinacridone Magenta (not to be confused with PR122), and the other is a plum-like purple, and is usually named Quinacridone Violet. This is an amazing, much-needed color, which might even find a place on some of the stricter limited palettes. Both major types are transparent, create gorgeous glazes, and tend to rank exceptionally well for lightfastness.

The lightfastness does vary from brand to brand, so this is an area where it is important to do your own lightfastness testing. Lightfastness can vary from decent to excellent, though PV19 can have some diminished lightfastness in tints (speaking of 7's and 8's on the blue wool scale). Lightfastness may be different in watercolor than in oils.

The rose version is a helpful pink which can be fairly deep in masstone and creates stunning cool pink glazes. Like Quinacridone Red, PR209, it is able to achieve unique candy colors in a glaze. It is both deeper and a bit more toward red-purple than PR209.

The Quinacridone Violet version retains a deep high chroma and is a saturated warm purple.

Information about PV19 from Bruce MacEvoy, Handprint Guide to Watercolors, General information about this class of pigments from Handprint,
Excellent in oil and acrylic, may be less LF in watercolor. May depend on pigment supplier. May darken in bright light.
Depending on the supplier this color receives highest marks for lightfastness (BWS 8’s). However some pigment manufacturers have a variety that shows fading (7’s) in tints. Considered to be ASTM I. This particular pigment was unfortunately not mentioned in Golden’s recent testing with mixing whites in oil. It may be worthwhile to examine a pigment in the same family, Quinacridone Magenta, PR122. There have long been rumors that the lightfastness of PV19 varies according to the pigment manufacturer, so it may be advisable to do one’s own lightfastness tests.
Transparent
Ranges from Transparent to Opaque in oils depending on the formulation. Most often found as transparent. For the yellow shade of red there are some opaque versions.
Lower Concern
Rossol’s work mentions that though it has low acute toxicity, the “longterm hazards are unknown.” Treat all pigments and paints with studio safety protocols.
Strong
Some paintmakers report 5-14 days in oil. However some dry very fast, in which case it may contain driers.
Very Fine
