Winsor & Newton Artists’ Oil Colors are made from the finest pigments and raw materials that provide an exceptional degree of tinting strength and mix-ability. The smooth consistency of these paints delivers superior handling qualities that retain brush or palette knife marks or it can be thinned to the very finest glaze. The vivid colors are pure, clean and bright. See the color chart for permanency ratings and a measure of transparency to opacity. Over 100 Artists’ Oil Colors available in 37ml (1.25oz) tubes.
