Art Spectrum® French Ultramarine is a rich, transparent blue. Developed in 1828 by the French chemist Jean-Baptiste Guimet, it is a synthetic but indistinguishable alternative to the costly pigment derived from Lapis Lazuli. In accordance with proven traditional methods of production, all Art Spectrum® Artists’ Watercolours are carefully stone milled to enhance the individual brilliance of each selected permanent pigment and to maximise its handling qualities. Successful watercolours depend on selecting the best quality paper, the permanence and brilliance of the pigments and the use of a wide variety of quality brushes.

Available in 10ml tubes. Series 1-4.

We do not recommend using Art Spectrum® Artists’ Watercolours as pans.
