Varieties of the color blue may differ in hue, chroma (also called saturation, intensity, or colorfulness), or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a blue or other hue mixed with white, a shade being mixed with black. A large selection of these colors is shown below.

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. 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 color defined as blue in the NCS or Natural Color System is an azure-like color. The Natural Color System is a color system based on the four unique hues or psychological primary colors red, yellow, green, and blue. The NCS is based on the opponent process theory of vision.

The "Natural Color System" is widely used in Scandinavia.

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.

The term tint and shade is used in its technical sense as used in color theory.

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").

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.

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.
