A high level of pigmentation provides good covering power and tinting strength. While it can't match the superior pigment load of Artists' Oil Colour, the Winton range is much stronger than many other artists' quality ranges.

The economical cost has been achieved through the use of moderately priced pigments rather than lessening the pigment content to an unacceptable level. Winsor & Newton formulation, manufacture and quality control ensure a product of absolute excellence.

The Winton range has a more uniform consistency than Artists' Oil Colour and is slightly stiffer. It offers excellent retention of brush and palette knife strokes.
