The way my code works now is that the Start and Stop button is one in the same. The button is green. What I would like to happen is that when I click Start and the button changes to Stop I would also like for the color to change to red and to flash. 

Sub startStopTimer()
    If Range("timer.button.label") = "Start" Then
        Range("time.stamp.start").Offset(Range("count.of.timestamps") + 1).Value = Now
        Range("timer.button.label") = "Stop"
    Else
        Range("time.stamp.start").Offset(Range("count.of.timestamps"), 1).Value = Now - Range("time.stamp.start").Offset(Range("count.of.timestamps"))
        Range("timer.button.label") = "Start"
    End If
End Sub
Thank you in advance for any help,
