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

In color printing, the shade of cyan called process cyan or pigment cyan is one of the three primary pigment colors which, along with yellow and magenta, constitute the three subtractive primary colors of pigment. (The secondary colors of pigment are blue, green, and red.) As such, the CMYK printing process was invented in the 1890s, when newspapers began to publish color comic strips.

Process cyan is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure cyan ink. A typical formulation of process cyan is shown in the color box at right. The source of the color shown at right is the color magenta that is shown in the diagram located at the bottom of the following website offering tintbooks for CMYK printing: .

Red, green and blue lights, representing the three basic additive primary colors of the RGB color system, red, green, and blue. Cyan light is composed of equal amounts of green and blue light.

The web color cyan, shown at the right, is one of the three secondary colors in the RGB color model, used for creating all colors on a computer or television display by mixing various combinations of red, green and blue light. The X11 name for this color is cyan; the HTML name for the same color is aqua. They are both composed of the same mixture of blue and green light, and are exactly the same color.

This tincture is sometimes also called ciel or simply celeste. It is depicted in a lighter shade than the range of shades of the more traditional tincture azure, which is the standard blue used in heraldry.^[9] It has been used rarely since the 17th century,^[10] gaining popularity after the First World War.

Verdigris is the common name for a green pigment obtained through the application of acetic acid to copper plates^[34] or the natural patina formed when copper, brass or bronze is weathered and exposed to air or seawater over a period of time. The name verdigris comes from the Middle English vertegrez, from the Old French verte grez, an alteration of vert-de-Grèce ("green of Greece"). Used as a pigment in paintings and other art objects (as green color) since ancient Greece, it was originally made by hanging copper plates over hot vinegar in a sealed pot until a green crust formed on the copper. The vivid green color of copper(II) acetate made this form of verdigris a much used pigment. Until the 19th century, verdigris was the most vibrant green pigment available and was frequently used in painting. Verdigris was sometimes used to illustrate cyan colors in early color wheels.^[35]

Viridian is a blue-green pigment, a hydrated chromium(III) oxide, of medium saturation and relatively dark in value. It is composed more of green than blue. Specifically, it is a dark shade of spring green, the color between green and cyan on the color wheel, or, in paint, a tertiary blue–green color. Viridian takes its name from the Latin viridis, meaning "green".^[37]

The first recorded use of viridian as a color name in English was in the 1860s (exact year uncertain).^[38]
