Created with the working artist in mind. Fast drying time while still allowing for reasonable working time before drying, most pigments will dry within five days. Rive Gauche Oil has a thick, homogenous texture and contains safflower oil, which reduces yellowing and produces vibrant and clear light colors. Sennelier has taken special consideration when using cadmium substitute pigments offering the same opacity and luminosity as genuine cadmiums. There are 32 single-pigment colors, these highly concentrated pigments provide more saturated colors and crisper color blends. Most colors have very good lightfastness and dry to a satin finish. Available in 40ml and 200ml sizes, opaque, semi-opaque, transparent and iridescent colors (40ml only).
