They are 4 color names instead of 3 and have different names.
The point is that the RRGGBB concept does not work in CMYK. So the methods will
start to be called setMagenta(int m); etc. But the concept is still the same as
the setRed(int r) versions is now.

I know. But the idea was never to do conversions, it was that we want to store 
colors of a frame background or whatever in CMYK. So we don't _have_ to convert
it. We print it in CMYK just like the user entered the values.
If we receive an eps from a print company and that has a specific background 
color that the rest of the page also has to have. Since otherwise we see a
square around the picture in a different color then the rest of the page.

In this case we have to allow the user to type the frame background color in
CMYK since otherwise the conversion will probably give a slightly different
color then the embedded eps which you can see on the printout.
