Red, green, and blue lights, representing the three basic additive primary colors of the RGB color system, red, green, and blue

The color defined as blue in the RGB color model, X11 blue, is shown at right. This color 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 precisely 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.[8] Its complementary color is yellow.

International Klein Blue

International Klein Blue pigment

International Klein Blue (IKB) is a deep blue hue first mixed by the French artist Yves Klein. IKB's visual impact comes from its heavy reliance on ultramarine, as well as Klein's often thick and textured application of paint to canvas. There is a legend that Klein patented the color, but in reality he simply submitted a Soleau envelope and never progressed to the patent stage.

Cyan, magenta, and yellow are the three subtractive primary colors used in printing

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. It is displayed at right.

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 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.

The Munsell color displayed is only approximate, 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.

Savoy blue, or savoy azure, is a shade of saturation blue between peacock blue and periwinkle, lighter than peacock blue.[14] It owes its name to the fact of being the color of the House of Savoy, a ruling dynasty in Italy from 1861 to 1946.

Having become a national color with the unification of Italy (1861), its use continued even after the birth of the Italian Republic (1946) with the name "Italian blue". An Italian-blue border was in fact inserted on the edge of the Presidential Standard of Italy and the use of the blue scarf for the Italian Armed Forces' officers, for the presidents of the Italian provinces during the official ceremonies and of the blue jersey for Italian national sports teams it was also maintained in the Republican era.

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,[29] 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.[30] Originally defined as the colors used on the American flag, the colors have since deviated.[29]
