This colour is brilliant for its multiple uses. When applied thinly the full bright beauty of the pigment is revealed in its undertone. Painters can use the masstone/undertone differences for some beautiful effects.; Sennelier gathers only the finest organic and inorganic pigments from around the world. These pure pigments are ground very slowly with extreme care to an extra-fine consistency. They are then combined at maximum concentration with an archival safflower oil to yield the highest possible tinting strength and a rich satin finish. This paint has a unique buttery texture.
