Series 1Rublev Colours Watercolors are made with the same pigments used by watercolor masters of the 17th to 19th centuries. The colors are genuine single pigment paints available individually in tubes and cakes. Apply Rublev Colours watercolor paint on paper or other absorbent surfaces prepared to accept water-borne paint. Clean up is easy with soap and water.

Bone Black is made from charred animal bone and horn but not from ivory. It is a neutral opaque black that has high tinting strength and is highly staining. The term 'ivory black' is currently applied to this same high-grade bone black by other watercolor manufacturers.
