Azure is a variation of blue that is often described as the color of the sky on a clear summer's day.

On the RGB color wheel, "azure" (color #007FFF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan. In the RGB color model, used to create all the colors on a television or computer screen, azure is created by adding a little green light to blue light. The complementary color of azure is orange.

In the X11 color system which became a standard for early web colors, azure is depicted as a pale cyan.

Etymology

The color azure ultimately takes its name from the intense blue mineral lapis lazuli. Lapis is the Latin word for "stone" and lazuli is the genitive form of the Medieval Latin lazulum, which is taken from the Arabic لازورد lāzaward, itself from the Persian لاژورد lāžaward, which is the name of the stone in Persian^[2] and also of a place where lapis lazuli was mined.^[3][4]

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, and the Portuguese and Spanish azul, Hungarian azúr 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 broach, gold and azure).^[5][6][7]

In Russian, "голубой" (goluboj, azure or cyan) and "синий" (sinij, blue or navy blue) are not two shades of the same color, but distinguished in the way red and pink are distinct colors in English. A similar distinction exists between "celeste" or "azzurro" (azure, but used to indicate shades of light blue) and "blu" (blue) in Italian and "ฟ้า (fah, sky blue) and น้ำเงิน (nam ngoen, blue) in Thai.

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.^[8]

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.

Distinction between indigo, azure, and cyan

All of the colors shown below in the section variations of azure are referenced as having a hue code of between 195 and 225 (the hue code is the h code in the HSV color space), signifying that these colors are tones of azure. The only exception, as noted below, is the web color azure which, with a color code of 180, is actually a tone of cyan.

Strictly speaking, according to the mathematical logic of the RGB color wheel, indigo colors are those colors with hue codes of between 255 and 225, azure colors are those colors with hue codes of between 195 and 225, and cyan colors are those colors with hue codes of between 165 and 195.
