Traditional Chinese watercolors are mineral and vegetable pigments, premixed with some kind of binder, mostly animal glue. They are used in the same way as the Western watercolors by adding some water and after painting they fix perfectly on the rice paper. The main feature of genuine Chinese watercolor painting is its luminosity and transparency and that’s what vegetable and mineral pigments are all about. The purer the pigments, the more subtle their tones and brilliance will be. The quality of the pigment is also affected by the glue used, its origin and color.
