Cmyk?

Will there be support for color adjustment in the manner of the CMYK?

CMYK is only used for printed colors, CMYK are the colors of inks used in printing.
For light, screens, monitors, etc, the RGB standard is used.

I understand. But I mean a kind of simulation, like making a choice of colors in Photoshop or here:

RGB:

CMYK:

I meant something like that …
