This neutral, non-staining primary blue will subtly modify most pigments. Considered a "mixing pigment", its transparent nature can cast a giant reticulating shadow. An inorganic pigment, it is considered non-staining (and low-tinting) and ideal for glazing methods. Its ability to create soft edges, to lift and to mix readily makes Cobalt Blue a valuable contribution to watercolour palettes. Light fastness: Excellent Low Staining Granulation: Yes Semi-Transparent
