If you want to minimize your maintenance issues use a constant for the starting point:

Sub colourcode()

    Const RO_START As Long = 2
    'any other fixed value...

    Dim tcol As Long, ro As Long, co As Long

    ro = RO_START
    co = 2
    tcol = 10

    For i = 1 To tcol
        ActiveSheet.Cells(ro, co).Interior.Color = RGB(0, 0, 0)
        ro = ro + 2
    Next

    ro = RO_START  'reset, avoiding repeating the 2

End Sub
