Change formatting of Cell when it is edited - vba

Question

I want to change the formatting of a cell if the value changes. I just need it to be shaded in.
I'm trying to use the following:
Private Sub Worksheet_Change(ByVal Target As Range)
Target.Interior.ColorIndex = 45
End Sub
However this is far too sensitive. For example if i delete a row, the entire row changes colour as technically it's a change. Even if I go into a cell, make no change and come out of it, it changes the formatting.
Is there anyway to edit the above so it only formats the cell's when the value has changed?
Thanks

I think you could use below code as a base for your further logic.
The idea is: we need to remember value before it is changed, so best to read it when some range is selected (since you are talking about single cell, I didn't consider ranges consisting of more cells). The value would be stored in global variable ValueOnEnter.
When the change is finally made, we compare values "before" and after", and if they differ, change the color.
Public ValueOnEnter As String
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Count > 1 Then Exit Sub
If Target.Value <> ValueOnEnter Then
Target.Interior.ColorIndex = 45
End If
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Count > 1 Then Exit Sub
ValueOnEnter = Target.Value
End Sub
