CELL FILL COLOR NOT HOLDING ON WORKSHEET

[rikvny02]

In the below code I am defining the sections of the worksheet id like to highlight. Why will cell fill color of the rest of the worksheet not hold. If I try to fill another cell it just goes back to no fill.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
With Sheets("raise")
.Cells.Interior.ColorIndex = xlColorIndexNone
Select Case Target.Address
Case "$C$7"
.Range("C16:h16").Interior.Color = RGB(0, 255, 0)
.Range("C7:h7").Interior.Color = RGB(0, 255, 0)
Case "$C$8"
.Range("c17:h17").Interior.Color = RGB(0, 255, 0)
.Range("c8:h8").Interior.Color = RGB(0, 255, 0)
Case "$C$9"
.Range("c18:h18").Interior.Color = RGB(0, 255, 0)
.Range("c9:h9").Interior.Color = RGB(0, 255, 0)
Case "$C$10"
.Range("c19:h19").Interior.Color = RGB(0, 255, 0)
.Range("c10:h10").Interior.Color = RGB(0, 255, 0)
Case "$C$11"
.Range("c20:h20").Interior.Color = RGB(0, 255, 0)
.Range("c11:h11").Interior.Color = RGB(0, 255, 0)
Case "$C$12"
.Range("c21:h21").Interior.Color = RGB(0, 255, 0)
.Range("c12:h12").Interior.Color = RGB(0, 255, 0)
End Select
End With
End Sub

Because of your second line of code:

.Cells.Interior.ColorIndex = xlColorIndexNone

What this is doing, as you select ANY cell, it removes ALL color from ALL cells, before going in to your CASE statement and formatting the appropriate cells.
So this is acting as a "reset" everytime you move cells.

If you remove that one line of code, all your color changes will be retained.
