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 blues available.

Artist’s Notes: Combine Ultramarine Blue and Mars Orange for a range of neutral, earthy greys. It creates lovely olive greens when combined with yellow ochres.

Paint Maker’s Notes: Ultramarine Blue was developed as a replacement to 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 is noticeably more intense than natural Lapis Lazuli.
