Marti, Thank you for replying.
I did attempt to apply a scaling factor to the L* value as I was feeding the L*a*b* values into lcms for conversion to RGB after reading the replies of Kai-Uwe and yourself. I found that no matter what scaling factor I used, all it changed was which swatches had the most error, but it didn't really reduce the sum of the errors. So, I graphed L* against the R error, G error, B error, the average of the RGB error, and the luminance of the RGB error to see if there was any correlation. Here are the graphs: http://www.flickr.com/photos/michael-litscher/sets/72157603452068860/detail/ If there was a correlation I would see a line or at least a curve in the data, but there is no discernible trend. Really, I do want this to work. I am not looking forward to converting everything over to use Microsoft's color management system. The spreadsheet is still available for download here: http://files.colormetrix.com/lcms_test.zip The Visual Basic code I use to call lcms from within the spreadsheet can be viewed in Excel by clicking on the Tools menu, selecting Macro, and then the Visual Basic Editor. Thank you for your time. Michael A.
