Holbein Duo-Aqua Oil is an artist quality watermixable oil paint made with water-soluble linseed oil. It has all of the handling characteristics of traditional oil paints but can be thinned or cleaned up with just water. These paints have a uniform drying time, and will hold brushmarks and dry to a lustrous sheen like traditional oils. Duo-Aqua is available in 83 colours, 75 of which offer optimum permanence. These 83 colours are free of pigments deriving from heavy metals; for painters who can't live without their Cadmiums and Cobalts, these colours are now available and are known as Duo-Aqua Elite Colours. They have the same working properties as the original Duo-Aqua colours and are formulated in the same manner; the only difference is the pigments.

This is a 110ml tube of Holbein Duo Aqua Permanent White, a titanium white with the same general handling qualities but with a barium sulphate additive which inhibits yellowing in early drying while reducing tinting power and increases transparency.
