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.

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.
