%C details. 

%D Just to give users a start we define some colors. While
%D switching fonts is as international as can be, thanks to the
%D mnemonics, naming colors is very interface dependant. To
%D support international setups, we define both english and
%D interface dependant colors. We use the color inheritance
%D mechanisms to implement the interface dependant ones.

%D First we define some simple primary \cap{RGB} and \cap{CMYK} 
%D colors. All colors are defined in \cap{RGB} color space.
