I'm not going to work out which of those colours are dark and which are
light, but this stripped down version should get you going

Private Sub Worksheet_Change(ByVal Target As Range)
Dim vLetter As String
Dim vColor As Long
Dim yColor As Long
Dim cRange As Range
Dim cell As Range

Set cRange = Intersect(Range("E2:E99"), Range(Target(1).Address))
If cRange Is Nothing Then Exit Sub


For Each cell In Target
vLetter = UCase(Left(cell.Value & " ", 1))
vColor = 0 'default is no color
yColor = xlColorIndexAutomatic
Select Case vLetter
Case "GF7"
vColor = 34
yColor = 2 ' white
Case "TX9"
vColor = 35
yColor = xlColorIndexAutomatic
End Select
Application.EnableEvents = False 'should be part of Change macro
cell.Interior.ColorIndex = vColor
cell.Font.ColorIndex = yColor
Application.EnableEvents = True 'should be part of Change macro
Next cell
End Sub

Thanks to David McRitchie for the event Macro below I am now able to
change
background colors of cells as they are written. I now found that I have
another problem, is there a way to get the font to change colors, as in
white
font with the
dark color of a cell and visa versa, a black font with lighter color
cells?

thanks, Nick
