Cyan (#00FFFF)

In this 1889 dictionary, cyan-blue is defined as the blue-green color corresponding to wavelengths from 487 to 505 nm, corresponding to what is today called cyan.

Cyan (pronounced /ˈsaɪæn/;[1] from Greek: κύανoς (transliterated: kýanos), meaning "blue") 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 previously known as "cyan blue".[2]

Some shades of color close to cyan in the cyan color range are baby blue, 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.[3]

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.

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.

In nature

  • Pure water is nearly colorless. However, it does absorb slightly more red light than blue, giving large volumes of water a bluish tint; increased scattering of blue light due to fine particles in the water shifts the blue color toward green, for a typically cyan net color.[6]
  • Cyanobacteria (sometimes called blue-green algae) are an important link in the food chain.
  • Cyanide derives its name from Prussian blue, a blue pigment containing the cyanide ion.

In human culture

Architecture

  • Cyan colored tiles are often used to pave swimming pools to make the water within them seem more inviting to swim in, by making the cyan color of their water seem more intensely colored.

Film

  • A silverless dye track used for soundtracks on 35mm film stock. Red light readers are required to read cyan soundtracks.[1].

Medicine

  • Cyanosis is an abnormal blueness of the skin, usually a sign of poor oxygen intake. i.e the patient is "cyanotic".

Simple English

This box shows the color cyan.
 

Cyan is the color halfway between blue and green on the color wheel. It is one of the primary (main) colors of ink in an inkjet printer, along with yellow and magenta.

Cyan is a secondary color of light, along with magenta and yellow. The primary colors of light are: blue, red and green. Cyan is made by mixing green and blue light.

Meaning of cyan

  • Cyan is associated with making someone feel better and protection, as well as being associated with good health from getting exercise by going swimming. This is because the water in a swimming pool is usually colored cyan from having chlorine bleach added to it. The tiles of a swimming pool are often colored cyan, which makes the cyan color of the water in a swimming pool even more intense.
  • Cyan is a restful, calming color that symbolizes relaxation, especially that shade of cyan called bright turquoise (shown below) which can be the color of the water in lagoons in tropical countries where people go swimming on their vacations.
  • That shade of cyan that is called medium aquamarine (shown below) is used for the uniforms of nurses and surgeons and also used to paint rooms in hospitals because it is regarded as a color that calms and relaxes the patients.
