You would need to know EXACTLY what color you are looking for.
Code:
Sub MoveFootnotesIntoText()
'Application.ScreenUpdating = False
Dim RngSrc As Range, RngTgt As Range, f As Long
For f = ActiveDocument.Footnotes.Count To 1 Step -1
With ActiveDocument.Footnotes(f)
Set RngSrc = .Range
Set RngTgt = .Reference
RngSrc.End = RngSrc.End - 1
If RngSrc.Font.Color = RGB(0, 112, 192) Then
RngTgt.Collapse wdCollapseStart
RngTgt.FormattedText = RngSrc.FormattedText
.Delete
End If
End With
Next
Set RngSrc = Nothing: Set RngTgt = Nothing
'Application.ScreenUpdating = True
End Sub
