Right click the appropriate sheet tab, choose View Code, and paste in the
following:


Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As
Boolean)
If Target.Address = "$A$1" Then '<<<< CHANGE ADDRESS
If Target.Interior.ColorIndex = 6 Then '<<< 6 = yellow
Target.Interior.ColorIndex = xlColorIndexAutomatic
Else
Target.Interior.ColorIndex = 6
End If
Cancel = True
End If
End Sub

Change the address from $A$1 to the appropriate cell and change the 6 to the
desired ColorIndex value (see VBA Help for a list of colors).

...
Is there a macro that will change the interior color of a cell on a
click or double click? And then change it back to the default if
clicked again. I want to be able to go back and forth.


Thanks
