What you describe seems to talk about faces, not colors.  Colors in
Emacs are not first-class citizens, they are attributes of faces.  So
I still don't understand why you cannot define faces for your package,
and define the colors for those faces via hex RGB values, as we do
when no existing color is exactly like we want.
