Rublev ColoursNatural Pigments introduces a new way of making traditional waterborne paint: Rublev Colours Aqueous Dispersions. Aqueous dispersions are pigments dispersed in water ready to be mixed with water-based mediums. These dispersions are especially made for use with traditional painting mediums, such as egg, casein, fresco, ...watercolors and distemper (glue tempera). They are also ideally suited for use with gesso for making toned grounds for drawing and painting.
