Black CMYK values are (80, 70, 70, 100); meaning it is composed of 80 of cyan, 70 of magenta, 70 of yellow and 100 of black. The closest hex code of the color is #000000 with RGB equivalent values (0, 0, 0). The CMYK system is the backbone of the color printing technology found in 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 the reproducibility of black CMYK depends on the quality of the paper, the printer and the inks in the machine.
Note: The hex code for black CMYK mentioned on this page is only an approximation; it has been calculated from the CMYK values. Hexadecimal and RGB color values are for screen and digital media while the CMYK model is used for printing and, therefore, the conversion of one to another is not perfect. Also, the way black looks on the screen (via the hex code) would be very different from how it appears printed on paper (via its CMYK values).
