Etymology
The color azure ultimately takes its name from the intense blue mineral lapis lazuli. Lapis is the Latin word for "stone" and l?zul? is the genitive form of the Medieval Latin l?zulum, which is taken from the Arabic ?????? l?zaward, itself from the Persian ?????? l??award, which is the name of the stone in Persian and also of a place where lapis lazuli was mined.
The name of the stone came to be associated with its color. The French azur, the Italian azzurro, the Polish lazur, Romanian azur and azuriu, the Portuguese and Spanish azul, Hungarian azúr, and the Catalan atzur, all come from the name and color of lapis lazuli.
The word was adopted into English from the French, and the first recorded use of it as a color name in English was in 1374 in Geoffrey Chaucer's work Troilus and Criseyde, where he refers to "a broche, gold and asure" (a brooch, gold and azure).
Azure also describes the color of the mineral azurite, both in its natural form and as a pigment in various paint formulations. In order to preserve its deep color, azurite was ground coarsely. Fine-ground azurite produces a lighter, washed-out color. Traditionally, the pigment was considered unstable in oil paints, and was sometimes isolated from other colors and not mixed. Modern investigation of old paintings, however, shows that the pigment is very stable unless exposed to sulfur fumes.
The use of the term spread through the practice of heraldry, where "azure" represents a blue color in the system of tinctures. In engravings, it is represented as a region of parallel horizontal lines, or by the abbreviation az. or b. In practice, azure has been represented by any number of shades of blue. In later heraldic practice a lighter blue, called bleu celeste ("sky blue"), is sometimes specified.
