Sub swapem()
For Each c In ActiveSheet.UsedRange
If c.Interior.ColorIndex = 35 Then
c.Interior.ColorIndex = 41
End If
Next
End Sub

Assume I have a worksheet where some (but not all !!) cells have a background color of light green.

How can I change at once (!) the background color of all those cells to light blue?

All other cells should remain unchanged.
