Pigment Name: PV23-Dioxazine Violet

Pigment Type: Organic

Properties

Dioxazine Violet is transparent and has very high tinting strength. It is a staining pigment that is very dark when used at full power.

Concentrated, it paints out nearly black, but it mixes with Titanium White to form bright, opaque tints of purple.

PV23 produces slightly redder shades than PV37. Because the hue can vary with the conditions of preparation and grinding, it may be offered in a red shade, blue shade, and so forth.

Permanence

Dioxazine Violet has a good lightfastness. There may be some concern about it fading or shifting in colour in tints and washes. Some artists have reported that PV37, a molecular variant, is more lightfast than PV23.

Toxicity

History

Two molecular variants of Dioxazine Violet, PV23 and PV37, are available. They have similar properties but mix slightly differently.
