This is using a SHADED view option (my standard while modeling)
As you can see it is hard to tell what is XRef'ed and what is live and editable in the current DWG.
This is the same model but swapped to SHADES OF GRAY and you can really see the highlighted lines ready to be edited. Try it out!
This only works in PARALLEL view - not PERSPECTIVE view. (View Cube Setting)
