Library Item is a different colour when placed on the page

[Twogargs]

I have a geometry item (a fancy comic word balloon) in my Library.  When I last opened my document, every instance of the item is now a paler color than the Library item.  Yet, if I open a brand new document, the Library Item is the correct color when placed.  What's going on with my original document?

Figured it out.  The Color Swatch that the Library item used for color had been altered, although its name was still the same, and thus the colors reflected the new Swatch instead of the old one.
