IF 'x & y' are Both Zero THEN colorize 'a'

[ChrisOK]

How do I edit the red area of code to do an IF THEN color?
IF H6 and I6 are both zeros
THEN colorize "E6" as blue (Interior.ColorIndex = 41)

(in the Select Case f, it changes "E6" to red if it sees a zero result...which is correct, *UNLESS* H6 and I6 are BOTH zeros....then, the user should not be penalized with a red rating -- because BOTH being zeros indicates there was no data that month to calculate....(so, turn the red back to blue before ending the run if H6 and I6 are true)....if it's false....then I'm lost in how to tell it to go ahead and leave it at red..? Can you help guide me with Select Case g?

    Dim c As Range, d As Range, e As Range, f As Range, g As Range
        For Each c In Range("E3:E3").Cells
        Select Case c.Value
            Case 0 To 1
                c.Interior.ColorIndex = 41
            Case 2 To 20
                c.Interior.ColorIndex = 4
            Case 21 To 30
                c.Interior.ColorIndex = 6
            Case 31 To 999999999
                c.Interior.ColorIndex = 3
            Case Else
