Apparently, my version of the LIST52 Documentation file does not match the 
List52.Com file that I have.  In the documentation, the author refers to a 
means to change the screen attributes (colors) which are stored at program 
offsets 13C, 13D, and 13F.  If you follow his instructions and it works you 
obviously have his version, if not then try the following:

Type:
Debug LIST52.COM
Type:
-D130          Look for the sequence 09 02 00 07 in Debugs response.  I found 
               it started (for me) at offset 144.

               Note the offset at which it starts.  Let's call it xyz.  Now 
               location xyz contains the color of the "special lines" at top 
               and bottom of the list52 screen and xyz+1 is the text line color 
               and xyz+3 contains the screen help menu color (contrary to the 
               version described by the doc where this is the background 
               color).
Type:
-Exyz          You will see a sequence ending in "09.".  If you want to change 
               from blue type the new color number in hex immediately after the 
               period and hit cr.

               In the same manner you can change the foreground and help menu 
               colors by invoking Exyz+1 and Exyz+3.
Type:               
-W             Writes edited file back to source disk.
Type:
-Q             To exit.

Sorry, couldn't find the location of the background color contol.
