Holbein Water Soluble Aqua DUO Oil Paint - 40 ml Tubes - at least 30% off - Winsor and Newton Griffin Fast Drying Oil Colour offers the excellent advantage of faster drying times compared to traditional oil colours. This means that the traditional oil techniques of both impasto and glazing can be done in considerably less time and a painting can be completed in a single session. Because alkyd resin has physical properties that differ slightly from those of traditional oils, the pigment load is somewhat different as well. Experienced painters will notice slightly greater transparency compared to Artists' Oil Colour. The colour has been formulated to offer the greatest degree of tinting strength possible (consistent with good handling properties), and to take full advantage of the true characteristics of each pigment. Speed of drying makes Griffin Colour ideal for using at college, art school or in art society environments and also for examinations, painting outdoors or on holiday.
