Ultramarine is a deep blue color and a pigment which was originally made by grinding lapis lazuli into a powder.The name comes from the Latin ultramarinus, literally "beyond the sea", because the pigment was imported into Europe from mines in Afghanistan by Italian traders during the 14th and 15th centuries.
Ultramarine was the finest and most expensive blue used by Renaissance painters. It was often used for the robes of the Virgin Mary, and symbolized holiness and humility. It remained an extremely expensive pigment until a synthetic ultramarine was invented in 1826.

Applications
Synthetic ultramarine, being very cheap, is largely used for wall painting, the printing of paper hangings and calico, etc., and also as a corrective for the yellowish tinge often present in things meant to be white, such as linen, paper, etc. Bluing or "Laundry blue" is a suspension of synthetic ultramarine (or the chemically different prussian blue) that is used for this purpose when washing white clothes. Also often found in make up such as mascaras or eye shadows.
Large quantities are used in the manufacture of paper, and especially for producing a kind of pale blue writing paper which was popular in Britain.[4] During World War I, the RAF painted the outer roundels with a color made from Ultramarine Blue. This became BS 108(381C) Aircraft Blue. It was replaced in the 1960s by a new color made on Phthalocyanine Blue, BS110(381C) Roundel Blue.
