Better late than never, I have made some improvements to my main utilities again. The color picker and the GETTINTANDSHADE function are more acccurate. I also added a new tool caled "Show Excel 2007 Color Details" which shows the Theme, Tint And Shade, Color number, the HTML number and RGB number of each of the 60 Theme Colors.
All of the above tools are in the 2007 version only. Download it here
