Prussian Blue is a synthetic organic pigment that was discovered by the paint maker Diesbach, apparently by accident, in Germany in the early eighteenth century. For many years, it was used not only as a colour in its own right, but also as a component of the original Hooker's Green. The other ingredient, gamboge, is highly fugitive, which is why many watercolours painted with Hooker's green have taken on a bluish tone with with age.  

It is a very transparent and heavily staining colour. It dries quite quickly in oil, and can therefore wrinkly if applied too quickly. It is suitable for use in oils, watercolour, and egg tempera. However, it shouldn't be used in conjunction with alkali substances, such as Lead White or Calcium Carbonate as it can turn brown, so it isn't suitable for fresco. For the same reason, it isn't used with acrylic resin binders due to their alkaline nature, so most paint manufacturers will replace Prussian Blue with a mixture of Phthalo Blue and black in their acrylic ranges. It requires a wetting agent to fully disperse into a binder.

Rohrer & Klingner Liquid Watercolour Gloss Intensifier 50ml Learn More

Zinc White, or Zinc Oxide, is an artificial mineral pigment that was first produced in France in the late 18th century. Its use in commercial watercolours as Chinese White pre-dates its inclusion in oil painting. It is a semi-opaque, lightfast pigment, which dries very slowly in oil. Of all white pigments, it produces the most brittle paint film, so is not recommended in large quantities for impasto techniques. However, it is a good addition to a palette which requires a less overwhelming white than Titanium White.

Cobalt Blue is an artificial mineral pigment, produced by the calcination of cobalt oxide and aluminium oxide. It has been widely used since the early 1800s, following its discovery by the French chemist Thenard at the beginning of the century. The name Cobalt has its roots in the German word Kobold, meaning imp or evil spirit. German miners specifically used this name in the late-Middle Ages, as the presence of Cobalt ore in the mines made the extraction of silver very difficult. They were possibly aware of the toxic properties of the mineral frustrating their efforts.

Cobalt remains a very popular colour today, and is present in most ranges of paints, being a semi-transparent pigment that is stable in all media. As a watercolour, all cobalt pigments tend to granulate. As an oil paint, it requires less oil content than most other pigments, and dries quite quickly. Like Cerulean Blue, some artists may choose to bind it with poppy oil, to avoid any possible colour changes brought about by the yellowish cast of linseed oil and the pigment's weak tinting strength.

Phthalo (Mona) Blue is a synthetic organic pigment, Copper Phthalocyanine, that has been in use since the 1930s. It has an extremely high tinting strength and is a staining colour, so cannot successfully be lifted in watercolour. It requires a wetting agent to fully disperse into a medium, and, when used at full strength, a copper sheen is visible in dried paint film. It is transparent, very lightfast, and has a medium-to-slow drying rate in oil.

Toxicity: C

Verdigris is an artificial pigment that dates from antiquity. Originally, it was produced by exposing copper to vinegar; nowadays acetic acid is used. It is acidic, so can contribute to the deterioration of paper supports. For this reason, it is more suited to oil or tempera painting than it is to watercolour. In tempera painting, it should be bound in animal glue or isinglass glue rather than egg york. When used in oil painting it should be held in a resin oil or balsam such as Venice Turpentine, as it can turn brown when ground directly into linseed oil. It is a fast-drying, transparent pigment, with a visible crystalline structure.
