Artist's Watercolour is a European style transparent watercolour which also preserves the brush handling qualities inherent in traditional Japanese watercolour techniques. It may be re-wetted easily like a pan colour. For this reason Holbein does not produce watercolours in pan form but allows artists to create their own selection. Fill the wells of a suitable palette with the desired colour selection. Permit to dry the wet the colour when needed.Features. Colour - Grey of Grey. Capacity - 5 ml.
