Stoneground Gouache - Ultramarine Blue

A vivid deep blue, Ultramarine is an invaluable choice for any artist’s palette and can be used in everything from illustration to botanicals, florals, and landscapes. Ultramarine Blue is arguably one of the most versatile and popular blue available.

Artist Notes: Combine Ultramarine Blue and Mars Orange for a range of neutral, earthy greys that make for interesting and expressive bi-chromatic works. Ultramarine Blue creates lovely olive green hues when mixed with Golden Ochre.

Opacity: Semi-Opaque

Paint Makers Notes: Ultramarine Blue was developed as a replacement for the prohibitively expensive Lapis Lazuli which, until the advent of synthetic Ultramarine in the 1830s, was one of the only blue pigments available to artists. Synthetic Ultramarine Blue pigment is more intensely blue than Lapis Lazuli as it reflects more light.
