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.
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 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 Polish lazur, the Italian azzurro, the Portuguese and Spanish azul, Hungarian azúr, all come from the name and color of lapis lazuli.
Azure evokes nature, stability, calmness and richness, among other aspects of blue symbolism.
