Mauve CMYK values are (20, 30, 0, 0); meaning it is composed of 20 of cyan, 30 of magenta and 0 of yellow and black. This translates to an approximate hex code #C7B2D6 and RGB values of (199, 178, 214). The CMYK system is the foundation of color printing technology that runs both large industrial and small desktop printers. Colors are created using only four inks - cyan (C), magenta (M), yellow (Y) and black (K). Please understand that mauve CMYK as it looks on the screen may not be reproduced exactly on printed paper not only because of the two different color models - hex and CMYK - but also because of the quality of the printer, the paper and the four inks.
NOTE: The mauve (CMYK) hex color code mentioned on this page is just an approximation. It has been calculated from the CMYK values. As you probably know, the CMYK color model is for print media while hex codes and the equivalent RGB values are for screen. The two can seldom be converted correctly. Additionally, mauve color displayed on the screen through its hex code, may look very different when printed (by the CMYK values).
