Varieties of the color cyan From Wikipedia, the free encyclopedia
The color cyan, a greenish-blue, has notable tints and shades. It is one of the subtractive primary colors along with magenta, and yellow.
The first recorded use of cyan blue as a color name was in 1879 ("cyan blue" being the name used for "cyan" in the 19th century).[1]
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 cyan that is shown in the diagram located at the bottom of the tintbooks for CMYK printing.[2]

The first recorded use of turquoise as a color name in English was in 1573.[25] Perhaps owing to sharing its name with a mineral, turquoise is currently a more common term in English than other cyan-like colors.[26]
Verdigris is the common name for a green pigment obtained through the application of acetic acid to copper plates[27] 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 Used as a pigment in paintings and other art objects (as green color) since ancient Greece, it was originally made by hanging copper plates over hot vinegar in a sealed pot until a green crust formed on the copper.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.[28]
