Compare Values In Two Cells - Highlight When There Is No Match

I have two cells with values that are strings.

I would like to know of a macro that can compare each two cells(start from E2 and compare with E3)to see if the values are NOT equal.

If they are equal, do nothing and if they are NOT, highlight the value.

Example:
compare E2&E3, E4,E5,E6,E7,.... if for example E2&E3, E4,E5,E6,E7,.... each hat same string, do nothing, but if they were not the same highlight it with red.

This code checks two cells and highlights one cell when there is duplicate, I like the opposite one, but don't know what to change!

Code:

Sub CompareCells() Dim r As Range, cell As Range Range
("E2", Range("E" & Rows.Count).End(xlUp)).Name = ("MyRange") Range("MyRange").Select
' clear all colors from selection Selection.Interior.ColorIndex = xlNone
' loop through cells and compare Set r = Selection Set r = Selection.Resize(r.Rows.Count + 1)
For Each cell In r If cell.Offset(1, 0).Value cell.Value Then
cell.Offset(1, 0).Interior.ColorIndex = 3 End If Next End Sub
