Cyan ( /ˈsaɪ.ən/[4] or /ˈsaɪ.æn/;[5] from Greek: κύανoς, transliterated: kýanos, meaning "dark blue substance")[6] may be used as the name of any of a number of colors in the blue/green range of the spectrum. In reference to the visible spectrum cyan is used to refer to the color obtained by mixing equal amounts of green and blue light or the removal of red from white light. As such, cyan is the complement of red in RGB and CMYK color models: cyan pigments absorb red light.
Cyan is also called aqua or blue-green, and was formerly known as "cyan blue".[7]
The first recorded use of cyan blue (as noted above, "cyan blue" was the name used for the color "cyan" in the 19th century) as a color name in English was in 1879.[8]
Some tones of color close to cyan in the cyan color range are teal, turquoise, electric blue and aquamarine.

The vivid cyan that is seen on an electronic display device (shown at right) is also referred to as electric cyan to distinguish it from the less vivid turquoise blue-like process cyan used in CMYK color printing (shown below). (Note: while the color is defined by definite RGB values, the display of the color will vary depending on the absolute color space used and the nature of the physical display device, e.g. computer monitor, and if this page is printed it is likely that the color shown will be far from representative.)
The web color aqua is an alias for electric cyan, that is, it is exactly the same color shown here as electric cyan.
To reproduce electric cyan in inks, it is necessary to add some white ink to the printer's cyan below, so when it is reproduced in printing, it is not a primary subtractive color. It is called aqua (a name in use since 1598) because it is a color commonly associated with water, such as the appearance of the water at a tropical beach.[9]

Cyan is also one of the common inks used in four-color printing, along with magenta, yellow, and black; this set of colors is referred to as CMYK as in spectrum(s).
While both the additive secondary and the subtractive primary are called cyan, they can be substantially different from one another. Cyan printing ink can be more saturated or less saturated than the RGB secondary cyan, depending on what RGB color space and ink are considered.
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.
