Potter's Pink is an artificial mineral pigment produced by roasting tin oxide with various other oxides. It was first discovered in the pottery region of Staffordshire in the late-1700s, and in the following century Winsor & Newton introduced Potter's Pink into their watercolour range under the name "pink colour". It went on to become a popular addition to watercolour palettes, offering an opaque, lightfast colour with a weak tinting strength and a medium level of oil absorption.

NY13:75640 Stil de Grain is a natural yellow pigment derived from unripe buckthorn berries, which were also once used to produce sap green pigment before the introduction of synthetic alternatives. Stil de Grain may also be known as brown lake, yellow lake, Persian lake, buckthorn lake, Dutch pink, yellow carmine and Italian pink. It has a weak tinting strength, and is very transparent, especially in oil. When mixed with oil, the pigment becomes saturated, darkening considerably in colour and drying very slowly, whereas in a water-based paint it is appears as a warm yellow. It is very fugitive to light, and compatible with all media, except lime. Larger quantities are available by request. Learn More

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.

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.

Burnt Sienna is a natural earth pigment that has been in use since antiquity. Our Burnt Sienna comes from Tuscany, and is produced by calcining Raw Sienna to temperatures of about 450 degrees Celsius. This process creates a rich warm colour and increases transparency. It also offers a good tinting strength, excellent lightfastness, and a fast to medium drying rate in oil. It is stable in all media but, like umber pigments, may be difficult to disperse in acrylic binders.

Cerulean Blue is an artificial mineral pigment that is prepared by heating a mixture of Cobalt Chloride and Potassium Stannate. It was first synthesised in the early nineteenth century, becoming more widely used from 1870, when Rowney introduced Coeruleum Blue into their range. It produces a very bright, clear, and unusually opaque blue, hence its name, which is derived from the Latin for "sky-blue", or perhaps "heaven-blue". It has a very low tinting strength meaning that, although it is stable in all media, some artists may choose to bind it in poppy rather than linseed oil, so that the colour isn't affected by the colour of the binder. It creates a fairly flexible paint film, and is a fast-to-medium drying pigment.

Terre Verte, sometimes known as Green Earth, is a natural earth pigment derived from clay coloured by iron silicate. As with other natural pigments, impurities can prevent it from fully dispersing in an acrylic binder, although it is a popular pigment in all other mediums. It has been in use since antiquity, providing excellent lightfastness and great transparency, with a low tinting strength. It requires a high volume of oil, and dries slowly to create a soft, flexible paint film. When calcined, Terre Verte becomes Burnt Green Earth.

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.

Yellow Ochre is a natural earth pigment that has been in use since prehistoric times. It is derived from iron-rich clay deposits that are present all over the world; our Yellow Ochre comes from the hilly regions around Verona, Italy. As a pigment, it is semi-opaque, extremely lightfast, and stable in all media. It has a medium to slow drying rate in oil, creating a tough, flexible paint film. Yellow Ochre is similar in composition to Raw Sienna, but whereas Yellow Ochre contains a higher proportion of clay, Raw Sienna contains a higher proportion of silica. As a natural material, the exact colour and qualities of the resultant pigments can vary, but generally this compositional difference creates a paler, more opaque Yellow Ochre, and a darker, more transparent Raw Sienna.

Caput Mortuum is a transparent, lightfast pigment that is stable in all media. Colours described as Caput Mortuum can vary greatly; our pigment is a soft purple-brown, made from a mixture of natural iron oxides. It is believed that Caput Mortuum has its roots in ancient Egypt, when colour was derived from remains that had been embalmed in asphaltum.

Gamboge is a natural tree resin, generally extracted by tapping of Garcinia trees, available as a powder and in the solid "pipe" form. One of the unique features of Pipe Gamboge is that it does not require a binding agent to be used as a paint. Instead, colour can be lifted with a wet brush, as from a watercolour pan. When used as a water colour, it gives a bright transparent golden yellow colour. It is highly transparent, fugitive to light, with a weak tinting strength. The powder can be dissolved in alcohol to colour resin-based varnishes. Gamboge was used from ancient times to dye the clothes and also to make a transparent yellow varnish for the colouring of wood, metals and leather.

Alizarin Crimson is a synthetic organic pigment that became available in 1868. It requires a wetting agent to disperse, and in oil it also absorbs a lot of liquid and dries very slowly to form a hard, brittle paint film. It is chemically identical to madder-root pigments and should be protected against UV light where possible as it can fade when applied onto a white ground, although it is less fugitive than its natural counterpart. Alizarin Crimson is a very transparent pigment, with a high tinting strength and slightly blue undertone.
