The color defined as blue in the RGB color model, X11 blue, is the brightest possible blue that can be reproduced on a computer screen, and is the color named blue in X11. It is one of the three primary colors used in the RGB color space, along with red and green. The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum gamut of colors that are capable of being represented on a computer or television set.

This color is also called color wheel blue. It is at 240 degrees on the HSV color wheel, also known as the RGB color wheel. It is a spectral color which lies at, or near, the short-wave (violet) end of the traditional "blue" and possibly was classified as "indigo" by Newton.[3] Its complementary color is yellow.

The color defined as blue in the CMYK color system used in printing, also known as pigment blue, is the tone of blue that is achieved by mixing process (printer's) cyan and process (printer's) magenta in equal proportions.

The purpose of the CMYK color system is to provide the maximum possible gamut of color reproducible in printing by the use of only three primaries.

The color indicated is only approximate as the colors of printing inks may vary.

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, its blue 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").

Deep sky blue is an azure-cyan color associated with deep sky blue.

Deep sky blue (Capri) is a web color.

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

The traditional name for this color is Capri.[39]

The first use of Capri as a color name in English was in 1920.[40]

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[41] 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 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, its shade of blue 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,[73] 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.[74] Originally defined as the colors used on the American flag, the colors have since deviated.[73]
