French Ultramarine is a deep blue color that is widely used in painting, particularly in oil painting and watercolors. This pigment gets its name from the fact that it was originally produced from the mineral lapis lazuli, which was imported from Afghanistan and transported to Europe through the Ultramarine trade routes. However, there are several other synonyms for this shade of blue, including Ultramarine Blue, Ultramarine Deep, Ultra Blue, Blue Ultramarine, and French Blue. Each of these synonyms refers to a slightly different shade of blue, but all of them are perfect for creating depth and richness in paintings.
