If you mean the swing lines in plan, the pen colour is controlled in the Model View Options.
The elevation opening lines I think are controlled in the door/window settings.
I am not 100% sure as I don't use Graphisoft doors and windows, so I would have to investigate.
If you are saying the lines look OK in Archicad, but are a different colour when you print then that is to do with pen sets.
I won't go into explaining that now, but if that is the problem, I will go into more detail.
