Cadmium Yellow Light is a beautiful primrose yellow that combines permanence with opacity. The zinc component makes this pale yellow slightly less lightfast than pure cadmium yellow, but it is still more permanent than most pigments.; 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.
