Rich Black. ich Black is used to refer to a mixture containing the four process colors: cyan, magenta, yellow, and black (CMYK) colors. This is necessary because no black ink is truly black, and the combination of the four inks will result in a denser black, or ârich black.â The printing industry has many definitions of rich black.
You can certainly choose a CMYK or HSL dialog in the fill and stroke and all colour pickers, but it converts all colors to 8 digit hex as you willl see in the bottom of the picker. Since RGB and CMYK spaces are both device-dependent spaces, there is no simple or general conversion formula that converts between them.
