RGB is probably good enough for Web browsers, but for some  
applications of CSS, how the colors look on paper will be much more  
important than how they look on a monitor. If you are familiar with  
(or have some control over)  the color space of the output device, you  
can get much more exact results with CMYK than you can by converting  
from RGB, which has a different gamut.
