An economical way to buy pigment colours, Kremer Studio Pigments are based on synthetic organic pigments mixed with a filler. The pigment is ground dry under stone rollers with marble dust / china clay to form a soft powder. They are easily dispersed, especially into water-based mediums, such as Lascaux Water Resoluble Medium and Kremer Acrylic Dispersions. Also work well when mixed with oils, such as Kremer Linseed oil and Kremer oil Mediums. Studio Pigments are bright and relatively lightfast.
