I'm working on an ASAP Utilities User Guide. When describing some of the worksheet function that use the colorindex property, I needed a good example of all available colors.
 So I wrote a quick macro to create a colorindex-table but enhanced it to show the colors in the same order as it is shown in the dropdown box:
 
Sub ColorTable() 
' variables Dim i                   
As Integer Dim j                   
As Integer Dim k                   
As Integer Dim sColorOrder         
As String Dim sLightColors        
As String Dim arColorOrder        
As Variant Dim iColorNr            
As Integer i = 0 
' these are the colors in de same order Excel shows ' them in the pulldown: sColorOrder = "1,53,52,51,49,11,55,56,9,46,12,10,14," & _
               "5,47,16,3,45,43,50,42,41,13,48,7,44,6," & _
               "4,8,33,54,15,38,40,36,35,34,37,39,2,17," & _
               "18,19,20,21,22,23,24,25,26,27,28,29,30,31,32"
 arColorOrder = Split(sColorOrder, ",", , vbTextCompare) 
' Light colors that will have a dark fontcolor: sLightColors = "|6|36|19|27|35|20|28|8|34|2|"
 Application.ScreenUpdating = 
False For j = 1 
To 7            
' loop rows  For k = 1 
To 8            
' loop columns   With Cells(j, k)
    iColorNr = arColorOrder(i)
    .Interior.ColorIndex = iColorNr
    .Value = iColorNr    
' is the color light, then make the textcolor darker    If InStr(1, sLightColors, "|" & iColorNr & "|") > 0 
Then     .Font.ColorIndex = 56  
'dark grey    Else     .Font.ColorIndex = 2  
'white    End If   End With   i = i + 1  
Next k 
Next j
 ' Give it a nice layout:
 With Range(Cells(1, 1), Cells(7, 8))
  .RowHeight = 20
  .ColumnWidth = 4
  .HorizontalAlignment = xlCenter
  .VerticalAlignment = xlCenter
  .Font.Bold = True
 End With
 Application.ScreenUpdating = True
End Sub
