You either do it with VBA event code, like so
Private Sub Worksheet_Change(ByVal Target As Range)
On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Range("A20")) Is Nothing Then
Select Case Target.Value
Case 1: Target.Interior.ColorIndex = 1
Case 2: Target.Interior.ColorIndex = 2
Case 3: Target.Interior.ColorIndex = 3
Case 4: Target.Interior.ColorIndex = 4
Case 5: Target.Interior.ColorIndex = 5
Case 6: Target.Interior.ColorIndex = 6
End Select
End If
ws_exit:
Application.EnableEvents = True
End Sub
'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.
