That seems like a good idea.

Hopefully you can just create a template specialization. Maybe we do
that already in some places. We should check whether this makes sense
for Gdk::Color in general. Maybe we need to fix Gdk::Color.

Or if nececessary you could probably create a custom PropertyProxy by
inheriting from the normal one. I don't think that the m4 macro actually
generates much code.
