A single pigment rich transparent blue with green undertones. Allegedly named because it was thought 'bluer than the sea', Ultramarine was originally made from semi-precious lapis lazuli. The current pigment was created by French chemist Guimet in 1828 as a synthetic, but chemically-identical alternative.
