A vivid and rich blue, Ultramarine Blue was first formulated in 1828 by chemist Guillemet as a synthetic reproduction of the expensive and rare mineral pigment Lapis Lazuli, whose color extraction process is also very labor intensive. Ultramarine Blue was the beautiful, affordable and stable alternative for artists. Opaque, very lightfast, and paints with a consistent smooth texture.
