The colour defined as blue in the RGB color model, X11 blue, is the most chromatic (colourful) blue that can be reproduced on a computer screen, and is the colour named blue in X11. It is one of the three primary colors used in the RGB colour space, along with red and green. The three additive primaries in the RGB colour system are the three colours of light chosen such as to provide the maximum gamut of colours that are capable of being represented on a computer or television set.
This colour is also called color wheel blue. It is at 240 degrees on the HSV/HSL colour wheel, also known as the RGB colour wheel. It is a spectral colour which lies at, or near, the short-wavelength end of the traditional "blue" and possibly was classified as "indigo" by Newton.{{cite book|last=Waldman|first=Gary|title=Introduction to light : the physics of light, vision, and colour|year=2002|publisher=Dover Publications|location=Mineola|isbn=978-0-486-42118-6|pages=193|url=https://books.google.com/books?id=PbsoAXWbnr4C&q=Newton+color+Indigo&pg=PA193|edition=Dover}} Its complementary colour 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 (colorfulness), spaced uniformly (in terms of human perception) in three dimensions in the Munsell color solid. In order for all the colors to be spaced uniformly, it was found necessary to use a color wheel with five, non-arbitrary, equally spaced primary colors: red, yellow, green, blue, and purple.
The color of the sample is the most chromatic (colorful) blue in the sRGB gamut that falls in the hue of 5B (primary blue) in the Munsell color space. In the 21st century, this blue is classified as an intermediate between azure and cyan.

Smalt has also been known under other names such as azurblau, Bohemian Blue, Dutch Ultramarine, enamel blue, Isenburg Blue. It was also known by many as Saxon Blue since the primary sources of cobalt ore used to make it were located in Saxony.
Smalt predates Thénard's Blue by several to many hundreds of years, which turned up as a result of the French government's famed search for a synthetic version of Lapis Lazuli. The Napoleonic administration appointed Louis-Jacques Thénard to find a substitute for Lapis Lazuli, and instead he found Cobalt Blue.

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").

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").

Resolution blue is a vivid blue color. The color name dates back to at least 2001, and came into wider use when the Resene Paints colors were used as one of the sources for the Xona Games Color List. Many of Resene's shades of blue and cyan are named after places in New Zealand's Marlborough Sounds, where Resolution Bay is located.
