Among the popular natural mineral pigments are azurite, malachite and cinnabar, but they all are very expensive and since the variety of the minerals are limited, so are the number of the colors.

They are produced in the same way as natural mineral pigments. It is highly durable and enables us to create wider range of color tone that natural mineral pigments would not have.
