The planet Uranus is colored cyan because of the abundance of methane in its atmosphere.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.However, it does absorb slightly more red light than blue, giving significant 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. A typical formulation of process cyan is shown in the color box on the right. Phthalocyanine blue is one such commonly used pigment. This is because real-world subtractive (unlike additive) color mixing does not consistently produce the same result when mixing apparently identical colors, since the specific frequencies filtered out to produce that color affect how it interacts with other colors. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure cyan ink. That is, process cyan is usually outside the RGB gamut, and there is no fixed conversion from CMYK primaries to RGB. Cyan printing ink is typically more saturated than the RGB secondary cyan, depending on what RGB color space and ink are considered. While both the additive secondary and the subtractive primary are called cyan, they can be substantially different from one another. In printing, the cyan ink is sometimes known as printer's cyan, process cyan, or process blue. Process cyan Cyan (subtractive primary)Ĭyan 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. 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. To reproduce the web color 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. The web colors are more vivid than the cyan used in the CMYK color system, and the web colors cannot be accurately reproduced on a printed page. In the HTML color list, this same color is called aqua. In X11 colors, this color is called both cyan and aqua. The web color cyan shown at right is a secondary color in the RGB color model, which uses combinations of red, green and blue light to create all the colors on computer and television displays. Cyan on the web and in printing The web colors cyan and aqua Cyan (additive secondary) Other English terms for this "borderline" hue region include blue green, aqua, turquoise, teal, and grue. In most languages, 'cyan' is not a basic color term and it phenomenologically appears as a greenish vibrant hue of blue to most English speakers. Further origins of the color name can be traced back to a dye produced from the cornflower ( Centaurea cyanus). It was formerly known as "cyan blue" or cyan-blue, and its first recorded use as a color name in English was in 1879. Its name is derived from the Ancient Greek word kyanos (κύανος), meaning "dark blue enamel, Lapis lazuli". Cyan is most often associated with peace, relaxation, healthcare, dreams, and spirituality. Mixing red light and cyan light at the right intensity will make white light.Ĭolors in the cyan color range are teal, turquoise, electric blue, aquamarine, and others described as blue-green. ![]() Cyan is the complement of red it can be made by the removal of red from white. ![]() In the additive color system, or RGB color model, used to create all the colors on a computer or television display, cyan is made by mixing equal amounts of green and blue light. In the subtractive color system, or CMYK color model, which can be overlaid to produce all colors in paint and color printing, cyan is one of the primary colors, along with magenta and yellow. It is evoked by light with a predominant wavelength between 490 and 520 nm, between the wavelengths of green and blue. ![]() ə n, - æ n/) is the color between green and blue on the visible spectrum of light. ![]()
