Dr. Ph Martin"s Hydrus Watercolor 1 oz. Crimson Lake

Evolving from decades of research and developement. Hydrus is fine art, lightfast, transparent watercolor at its best in a bottle! This liquid product delivers the same brilliance and permanency of traditional watercolor that one finds in a tube. Watercolorists can be confident because Hydrus is made from the finest art pigments (i.e. quincadora, phthalonice). They also enjoy the freedom of blending and intermixing while maintaning the transparency and luminocity of the color. Hydrus can even be used for technical pen, calligraphy fountain pen, and airbrush work where transparency of pigment is desired."
