Pigment Information

This color contains the following pigments:

PV23-Dioxazine Violet

PV16-Manganese Violet

PBr15-Details Unknown


Pigment Name

PV23-Dioxazine Violet

Pigment Type

organic

Chemical Name

carbazole dioxazine

Chemical Formula

C34H22Cl2N4O2

Properties

Dioxazine Violet is transparent and has very high tinting strength. It is a staining pigment, very dark valued when it is used at full strength. 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 red shade, blue shade, and so forth.

Permanence

Dioxazine Violet has good lightfastness. There may be some concern about it fading or shifting in color 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.


Pigment Name

PV16-Manganese Violet

Pigment Type

inorganic

Chemical Name

manganese ammonium pyrophosphate

Chemical Formula

(NH4)2Mn2(P2O7)2 - Mn3(PO4)2 * 3H2O or H4O7P2H3NMn

Properties

Manganese Violet is a semi-transparent, bluish-violet pigment with a discrete opacity and low tinting strength. It is the reddest of the violets, and it covers and dries well in oil and tempera. It also performs well in pastel, encaustic, and watercolor. Manganese Violet is not well suited for fresco or acrylic painting. There can be significant differences in color across brands. It shares similar properties with bluish shades of Cobalt Violet.

Permanence

Manganese Violet has excellent permanence and lightfastness, and it is one of the most lightfast, balanced violets in watercolor form.

Toxicity

Manganese Violet is highly toxic if inhaled and moderately toxic if ingested.

History

This pigment was developed in 1868 by E. Leykauf to replace the more expensive Cobalt Violet. It was not offered as an artists’ pigment until 1890.
