Azure is a blue-cyan color on the HSV color wheel (Hue, Saturation, Value), also known as the RGB color wheel, at 210 degrees. Azure is the hue that is halfway between blue and cyan. Azure is one of the tertiary colors on the HSV color wheel. Its complementary color is orange.[3]
The word Azure is a near synonym for the color blue. Commonly it refers to a bright blue, resembling the sky on a bright, clear day.
The etymology of the word azure has been traced back to the Persian word لاژورد "Lazheward"[4] , which is the name of a place in northeastern Afghanistan that in ancient times was the main source for lapis lazuli, a semi-precious rock with a vivid blue color. The word was adopted into French (as l'azur, the initial /l/ being understood as 'the') by the twelfth century. Today it is found in all Western European languages. It 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]
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.
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]
In some color systems, azure is defined more specifically. In the X11 color system which became a standard for early Web colors, azure is a pale cyan color.
United Nations blue, as it's called by the United Nations,[9] is the medium bright azure color of the Flag of the United Nations and of the helmets worn by the United Nations peacekeeping forces.
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 "azzurro" (azure, but used to indicate various shades of light blue) and "blu" (blue) in Italian and "ฟ้า (fah, sky blue) and น้ำเงิน (nam ngoen, blue) in Thai.
