Aqua (from Latin: aqua for water) is a greenish-blue color, a variation of the color cyan. The web color aqua is identical to the web color cyan, also sometimes called electric cyan, one of the three secondary colors of the RGB color model used on computer and television displays. In the HSV color wheel aqua is precisely halfway between green and blue. However, aqua is not the same as the primary subtractive color process cyan used in printing.
The words "aqua" and "cyan" are used interchangeably in computer graphics, and especially web design, to refer to the additive secondary color "cyan". Both colors are made exactly the same way on a computer screen, by combining green and blue light at equal and full intensity on a black screen. Traditionally, that color, defined as #00FFFF in hex, or (0,255,255) in RGB, is called "cyan", but X11 color names introduced the alternative name "aqua". Later, W3C popularized the name by using it in the named color palette of HTML 3.2 specifications.
