Azure pigment

Azure (/ˈæʒər, ˈeɪʒər/ AZH-ər, AY-zhər, UK also /ˈæzjʊər, ˈeɪzjʊər/ AZ-ure, AY-zure)[2][3][4] is a variation of blue that is often described as the color of the sky on a clear day.

On the RGB color wheel, "azure" (hexadecimal #0080FF) 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.

## Wrapping the spectrum into a color wheel[edit]

In a color proximity sense, a primary color has a color range of 120° (60° on each side of the color's hue) and any color has to be within that range to be considered a variation of that color. Secondary colors have a color range of 60° (30°), tertiary colors have a color range of 30° (15°), quaternary colors have a color range of 15° (7.5°), quinary colors have a color range of 7.5° (3.75°), and so on. Because azure is located at a hue angle of 210°, it has a tertiary color range of 195° and 225°, and any color out of this range is more related to cyan or blue than azure. If the visible spectrum is wrapped to form a color wheel, azure (subtractive primary) appears midway between blue and cyan, or violet and spring green:

### Distinction between indigo, azure and cyan[edit]

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 150 and 210.

This color is on the color wheel (RGB/HSV color wheel) halfway between azure and cyan.

The traditional name for this color is Capri.[11]

The first use of Capri as a color name in English was in 1920.[12]

The color Capri in general is named for the azure-cyan color of the Mediterranean Sea around the island of Capri off Italy, the site of several villas belonging to the Roman Emperor Tiberius, including his imperial residence in his later years, the Villa Jovis. Specifically, the color Capri is named after the color of the Blue Grotto on the island of Capri[13] as it appears on a bright sunny day. Today the island of Capri is a resort island popular with tourists.

The name deep sky blue for this color did not come into use until the promulgation of the X11 color list in 1987.

The hues of the Munsell color system, at varying values, and maximum chroma to stay in the sRGB gamut

The color defined as blue in the Munsell color system (Munsell 5B) is shown at right. The Munsell color system is a color space that specifies colors based on three color dimensions: hue, value (lightness), and chroma (color purity), spaced uniformly (according to the logarithmic scale which governs human perception) in three dimensions in the Munsell color solid, which is shaped like an elongated oval at an angle. In order for all the colors to be spaced uniformly, it was found necessary to use a color wheel with five primary colors: red, yellow, green, blue, and purple.

Munsell can only be displayed approximately on a computer screen, as these spectral colors have been adjusted to fit into the sRGB gamut. In the 21st century, this hue is classified as an intermediate between azure and cyan.

Celtic blue is a shade of blue, also known as glas celtig in Welsh, or gorm ceilteach in both the Irish language and in Scottish Gaelic. Julius Caesar reported (in Commentarii de Bello Gallico) that the Britanni used to colour their bodies blue with vitrum, a word that means primarily "glass", but also the domestic name for the "woad" (Isatis tinctoria), besides the Gaulish loanword glastum (from Proto-Celtic *glastos "green"). The connection seems to be that both glass and the woad are "water-like" (lat. vitrum is from Proto-Indo-European *wed-ro- "water-like").

Penn Blue is one of the official colors of the University of Pennsylvania, along with Penn Red. While the school colors were defined by 1910,[41] university history points to earlier times when the colors may have been chosen, including a possible visit by George Washington to the University, where students used the color of his tunic to determine school colors or a track meet where Penn athletes declared that they would wear the colors "of the teams we beat," which would be those of both Harvard University and Yale University.[42] Originally defined as the colors used on the American flag, the colors have since deviated.[41]
