I have a problem that just started and is now in all my drawings.
When I open a drawing with an X reference that has many different color lines, when I open the drawing all the xref lines are very dark and I use a black screen. Is there a setting that I accidently changed that will not allow the xref lines to be the color that is indicated.
 
Thanks for the help.

What version of Autocad are you using? If you're using one of the latest versions, you can control the brightness of xrefs from within your Options dialog. Open up the Options dialog and go to the "Display" tab. There is a slider in the lower right corner, under "Fade Control", "Xref Display", that you can adjust to make xrefs appear darker or lighter. Adjust to your liking.
