One way:

Put this in your worksheet code module (right-click the worksheet tab
and choose View Code):

Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
Range("B1,A5").Interior.ColorIndex = _
Range("A1").Interior.ColorIndex
End Sub

Note that the change won't take effect until you change the selected
cell.
