Five generations of chemists in the Blockx family have been working since 1865 to perfect the Blockx Oil Colors. Today they are still ground on stone rollers and mixed with poppyseed or linseed oil, and no additives or fillers whatsoever.
Color Swatch created using heavy application/medium application/50% tint and was applied on acrylic primed canvas (7 oz) material.
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.
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.
Two molecular variants of Dioxazine Violet, PV23 and PV37, are available. They have similar properties, but mix slightly differently.
Dioxazine Purple, Chromothal Violet, Mauve, Carbazole Violet.
