LaTeX color and ICC color profiles
I think the simplest is to put your definitions in a local package so they can easily be shared between documents and customised to different profiles.
In your document put something like
\usepackage[CoatedFOGRA39]{mycolor}
if you specify a profile that you have set up, relevant definitions are made, otherwise you get an error. mycolor.sty
could look something like this:
\RequirePackage{color}
\DeclareOption{CoatedFOGRA39}{\def\mycolor{CoatedFOGRA39}}
\def\mycolorprofileA{CoatedFOGRA39}
\ProcessOptions\relax
\ifx\mycolor\@undefined
\PackageError{mycolor}{No color profile declared}{declare a color profile}
\fi
\ifx\mycolor\mycolorprofileA
\DefineNamedColor{named}{mycolor}{cmyk}{0.3203,0.1602,0.1172,0.0000}
\fi
The above just declares one colour in one profile, but it could be extended...
