Allocating and using colours...

["David J. Singer" <doc deadvirgins org uk>]

According to the manuals, there seems to be a number of different ways
of defining and using colours and graphics contexts and I'd appreciate 
some guidance as to the "best" way to do this.

Back in Gtk 1.2 I used to do something like:
 
   GdkColor color_red = {0, 65535, 0, 0 };
   ...
      gdk_color_alloc(gdk_colormap_get_system(), &color_red);
      gc_values.foreground = color_red;
      gc = gdk_gc_new_with_values( pixmap, &gc_values, GDK_GC_FOREGROUND );

which worked fine, was quick and easy, but always struck me as a bit of a hack. 
Is is OK?  How should I be doing this...
