This is a semi-opaque warm, reddish violet that is very dark in mass tone. An essential colour for artists who need a clean mixing, single pigment, warm violet.; 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.
