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. In [[X11 color names|X11 colors]], this color is called both cyan and [[aqua (color)|aqua]]. In the HTML color list, this same color is called aqua.

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. 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. 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.<ref>Maerz and Paul ''The Dictionary of Color'' 1930 (see under Aqua in Index, page 189)</ref>
