Zotero can't do this but I think it might be possible to use a Word wildcard/special character search&replace to change the color of all Zotero citation (i.e. Word fields inserted by Zotero)
You can use macro to do this Function ZeterColor() For Each aField In ActiveDocument.Fields If InStr(aField.Code, "ADDIN ZOTERO_ITEM CSL_CITATION") > 0 Then aField.Select Selection.Style = ActiveDocument.Styles("CitationFormating") End If Next aField End Sub
Function ZeterColor()
For Each aField In ActiveDocument.Fields
If InStr(aField.Code, "ADDIN ZOTERO_ITEM CSL_CITATION") > 0 Then
aField.Select
Selection.Style = ActiveDocument.Styles("CitationFormating")
End If
Next aField
End Sub
