Cyan (IPA: /saɪæn/; from Greek κυανός / kyanos, meaning "blue") may be used as the name of any of a number of a range of colors in the blue/green part 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 systems: cyan pigments absorb red light.
Cyan is also called aqua or blue-green, and was previously known as "cyan blue".
Some shades of color close to cyan in the cyan color range are baby blue, teal, turquoise and aquamarine.
