I was experimenting with the color tables, trying to figure out what would
print the best without fully understanding it yet, and suddenly my purple is
blue and peach is light peach. That's actually better than it was originally,
when everything turned cyan or magenta.
Undo doesn't undo these changes, and neither does going back to an earlier
version of the file. Is there any way to correct this kind of catastrophe?
I've also tried exporting and pulling it up in PhotoShop and InDesign, but I'm
not familiar enough with them yet to be able to do what I want ...
