Hi BD3

You can run it in a event in the thisworkbook module

This event will run when you save your workbook

Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
Dim sh As Worksheet
For Each sh In ThisWorkbook.Worksheets
On Error Resume Next
sh.UsedRange.SpecialCells(xlCellTypeBlanks).Interi or.ColorIndex = 3
On Error GoTo 0
Next sh
End Sub

See this page about events
