Kuretake Gansai Tambi Watercolor Pan - Lilac

Pigment Information

This color contains the following pigments:

PW6-Titanium White

PV23-Dioxazine Violet

PB1-Victoria Blue

Pigment Name

PW6-Titanium White

Pigment Type

inorganic

Chemical Name

titanium dioxide

Chemical Formula

TiO2

Properties

Titanium White is the most brilliant of the white pigments. It is considered an all purpose oil color useful in all techniques and the best all around white. Its masstone is neither warm nor cool, placing it somewhere between Lead White and Zinc White. It is less prone to cracking and yellowing than Lead White, but it still yellows easily. Titanium White dries slowly in oil form, more slowly than Lead White but more quickly than Zinc White. It is opaque in oil and acrylic forms and semi-opaque in watercolor form. This pigment has good chemical stability, and its tinting strength is superior to both Lead White and Zinc White.

Permanence

Titanium White has excellent permanence and lightfastness.

History

Titanium is the ninth most abundant element in the Earth's crust, however mineral deposits that are economical to mine are less common. Titanium dioxide was first discovered in 1821, although it could not be mass produced until 1919. Widespread use of the pigment began in the 1940s. Since that time, it has become the most commonly used white pigment. The name comes from the Latin word Titan, the name for the elder brother of Kronos and ancestor of the Titans, and from the Greek word tito, meaning day or sun.

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.

History

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

Pigment Name

PB1-Victoria Blue

Pigment Type

organic

Properties

Victoria Blue is a brilliant, transparent reddish blue dye, which can be laked as a pigment. Because its tinting power is not so overwhelming as that of Phthalo Blue pigments, it still has a place on the designer's palette, even though Phthalo Blue (Red Shade) might be considered superior in many respects.

Permanence

Victoria Blue is considered fugitive. It should be used primarily in works that are prepared for reproduction, not for permanent display, when there is a need for a transparent blue pigment with less tinting power than Phthalo Blue.

History

Victoria Blue, one of the oldest synthetic blue dyes, is used in papers, inks, and textile dyes. Although much more reddish in tone, it was an early synthetic replacement for indigo dyes from natural sources at a time when blue was still in great demand in textiles.
