Did you read this fine document:

https://developer.gnome.org/gtk3/stable/gtk-migrating-GtkStyleContext-css.html

I am not doing widget development, but my impression is that the
gtk_style_context_lookup_color() function mentioned at the bottom may be
what you need, maybe together with GTK_STATE_FLAG_INSENSITIVE for
gtk_style_context_get().

Of course, when writing new widgets, it may be a good idea to inspect
some source code of existing widgets...
