Er, yes, I was actually! Stuart, have you any experience of Applescript?
If you paste the following into a blank applescript document, and save it as an application, you should be able to drop Quarks onto it and it will change the colour of the Normal paragraph style to Black.
Test it first on a couple of documents you've set up that don't matter!!
Just thought - it may be that what I should have done is changed the colour of the 'Normal' character style... Let me know if so, and I can change it (or you can have a go!)
If this is all gibberish, email me and I'll try and help. Bit busy with work at the moment but will try and reply!
OK, here's the script:
on open docList
set x to 1
repeat number of items in docList times
tell application "QuarkXPress"
open (item x of docList) use doc prefs yes remap fonts no
tell document 1
set color of character attributes of style spec "Normal" to "Black"
close saving yes
end tell
end tell
set x to x + 1
end repeat
end open
