Please see <http://en.wikipedia.org/wiki/CMYK_color_model#Conversion>, for

Please also note that the only sensible reason to use CMYK on the Web is to
enable wide-gamut printing. So, besides a way to convert CMYK for display we'd
need a way to convert it directly to printer color space, as
CMYK->display->printer will lose a lot of quality regardless of how well it is
performed, simply because printer gamut is different.

See <https://bugs.webkit.org/show_bug.cgi?id=12205#c6> for what Opera does with
CMYK CSS colors - there's a good chance that they do the same with images.
