Answer 1

In the CSS Color Module Level 4 of the W3C as of 5 November 2019, there is a function called device-cmyk that can be used to define a device dependent CMYK color value.

Example:

color: device-cmyk(0 81% 81% 30%);

The function returns an RGB value that the device calculates by trying to convert the CMYK color to an RGB value that matches the CMYK color as close as possible.

Note: I can't find anything regarding the browser support. I guess that no browser is currently supporting this.
