Conditional Formatting in VBA, based on functions

Question

I have some (semi) complex conditional formatting to do in Excel. I can get it working no problem using the menu, but I want to do it programmatically because I want it applied across multiple sheets (copy, paste as format does not work).

I tried recording a macro while I set up the CF to get the code, but it doesn't record that type of entry.

Here are the rules I'm applying, currently to the range: =$1:$65536

=OR(COLUMN()=1,COLUMN()=2,ISBLANK($B1))
=AND(LEFT($A1,6)="Base (",A1>100)
=AND(LEFT($A1,6)="Base (",A1>=75,A1<=100)
=AND(LEFT($A1,6)="Base (",A1>=50,A1<75)
=AND(LEFT($A1,6)="Base (",A1<50)
=$B1-9.999  (current cell is less than this value)

Like I said, I can copy this manually by copying a whole column from one sheet to the next, but I can't copy it across all sheets, and I'd like to find a way to do it as a Macro so it can easily be applied to new workbooks (which tend to have 10-15 sheets).

Sub DoCFRules()

    Dim rng As Range
    Set rng = ThisWorkbook.Sheets("Sheet1").Cells

    rng.Parent.Activate
    rng.Cells(1).Select 'Important!

    ApplyCF rng, "=OR(COLUMN()=1,COLUMN()=2,ISBLANK($B1))", RGB(0, 255, 0)
    ApplyCF rng, "=AND(LEFT(A1,6)=""Base ("",A1>100)", RGB(255, 0, 0)
    'etc...

End Sub

Sub ApplyCF(rng As Range, sFormula As String, clr As Long)
    With rng.FormatConditions.Add(Type:=xlExpression, Formula1:=sFormula)
        .Interior.Color = clr
    End With
End Sub
