How can I use an IF statement to change cell background color format where more than 3 color options are needed?

Hello experts,

I need help formatting a cell to display a different color for each day of the week:

Mon      Yellow
Tue      Blue
Wed      Pink
Thu      Green
Fri      Gold

I’m thinking of something like this:

Cell A2 contains the day, e.g. Mon.  Cell B2 is a formatting formula for cell A2, e.g.:
=if(a2=“Mon”, cell.Interior.ColorIndex=Yellow)

Can I do this?  (Conditional formatting in my Excel 2003 limits me to 3 conditions.)
If not, is there a workaround?  (I would prefer not to use VBA.)

Thanks,
Gary

Shows what happens when you don't test ... I used index and shouldn't!

The test range is limited to a1:a100 but of course change that as required

Private Sub Worksheet_Change(ByVal Target As Range)
Dim cel As Range
    For Each cel In Intersect(Me.Range("A1:A100"), Target)
        If cel.Value = "Mon" Then
            cel.Interior.Color = 65535
        ElseIf cel.Value = "Tue" Then
            cel.Interior.Color = 16711680

        End If
    Next

Add a worksheet macro for example right click the tab then paste:

And no need for column B in this case

Private Sub Worksheet_Change(ByVal Target As Range)

Missed you stated the actual colurs:

    For Each Cell In intersect(Range("A2:A100"), target)

        ElseIf Cell.Value = "Tue" Then
            Cell.Interior.ColorIndex = 16711680
        ElseIf Cell.Value = "Wed" Then

Thanks, Chris, for the Macro approach.

This will be a worksheet where rows will be added.  I want the cell color to show upon entry without running a macro each time.  Can I do this with a formula?

The macro is dynamic so try it ... whenever you edit the cells the color changes.

A shorter version of Chris's code, just for fun. As he said, right click the tab, click View Code then paste.

Private Sub Worksheet_Change(ByVal Target As Range)
Dim i As Long
application.screenupdating=false
    For Each Cell In Intersect(Range("A2:A100"), Target).cells
        For i = 3 To 9
             If UCase(Cell) = UCase(Format(i, "ddd")) Then
                Cell.Interior.ColorIndex = i
                GoTo nxtCl
            Else
                Cell.Interior.ColorIndex = xlNone
            End If
        Next
nxtCl:
    Next
application.screenupdating=true
End Sub

And to handle errors when you update non A cells:

Private Sub Worksheet_Change(ByVal Target As Range)
Dim i As Long
application.screenupdating=false

If Not Intersect(Target, Range("A2:A200")) Is Nothing Then
    For Each Cell In Intersect(Range("A2:A100"), Target)
        For i = 3 To 9
             If UCase(Cell) = UCase(Format(i, "ddd")) Then
                Cell.Interior.ColorIndex = i
                GoTo nxtCl
            Else
                Cell.Interior.ColorIndex = xlNone
            End If
        Next
nxtCl:
    Next
End If
application.screenupdating=true

End Sub

Since I was not explicit, you wanted to avoid using VBA and the bottom line is that cannot be done, (in 2003 whereas later versions allow more CF entries.  IN this case whatever approach you use will require a macro and the change event handler uses the built in methods so is perfect for the job.

I'm sorry for abandoning you all on this one.  I spent time trying the VBA solution but was not totally satisfied (especially with my comfort level with supporting VBA at this time).  I agree with your split, these suggestions, I believe are the answer.

Thanks,
Gary
