This article is about the color. For other senses of this word see cyan (disambiguation).

Cyan (from Greek κυανοs, meaning "blue") is the name of any of a number of colors. One definition is a color made by mixing equal amounts of green and blue light (it also is a pure spectral color). As such, cyan is the complement of red: cyan pigments absorb red light. Cyan is sometimes called blue-green or turquoise and often goes undistinguished from light blue. Cyan is often referred to as "Electric Blue".

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.

Note that while both of these colors are called cyan they are actually substantially different from one another. Cyan printing ink is much less vivid--indeed, CMYK printing technology cannot accurately reproduce pure cyan as described above (100% blue + 100% green) on paper.
