Adapt blink code to blink lowest # in column

How can I adapt this code to make the lowest number in a column of numbers blink. Thank you in advance.

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Value = 55 Then
For n = 1 To 10
Target.Interior.Color = vbRed
Delay (0.04)
Target.Interior.ColorIndex = xlNone
Delay (0.04)
Next n
End If
End Sub

Sub Delay(rTime As Single)
'delay rTime seconds (min=.01, max=300)
Dim oldTime As Variant
'safety net
If rTime < 0.01 Or rTime > 300 Then rTime = 1
oldTime = Timer
Do
DoEvents
Loop Until Timer - oldTime > rTime
End Sub
