Change Active Cell Color According To Name Above

Here is a screen shot of what I have:

I want to be able to enter the name from the above 4 cells (B3,B4,B5,B6) IN THAT COLUMN, and have the active cell change color accordingly.

If I am in cell C7 and start to type "PUBLIX" It should turn red in color. It does not because the code looks to a specific cell (example: B3). What can I change in my code to give the results I desire?

I have conditional formatting code below I copied from THIS site:

Private Sub Worksheet_Change(ByVal Target As Range)
' Multiple Conditional Format
Dim rng As Range
' Only look at single cell changes
If Target.Count > 1 Then Exit Sub
' Adjust Format range to suit
Set rng = Range("B7:H74")
' Only look at that range
If Intersect(Target, rng) Is Nothing Then Exit Sub
' Adjust conditions to suit
Select Case Target.Value
Case Range("B6").Value
Target.Font.ColorIndex = 50 ' Green
Case Range("B5").Value
Target.Font.ColorIndex = 3 ' Blue
' Case "Super"
' Target.Font.ColorIndex = 6 ' Yellow
Case Range("B4").Value
Target.Font.ColorIndex = 13 ' Purple-ish
Case Range("B3").Value
Target.Font.ColorIndex = 5 ' Red
' Case "Corporate"
' Target.Font.ColorIndex = 37 ' Light Blue
End Select
End Sub
