blank cell color VBA

[matiiss]

hey, I am trying to fill in blank cells with color, but the way I am doing it, it does not work.
the lines I am using:

If Wks1.Cells(j, 4).Value = "" Then
Wks1.Cells(j, 4).Interior.ColorIndex = 3
End If

Should it work?

Is there another way how to fill in blank cells with color?

Thank you very much!
