You are using .xls. I don't know the details of the file format, but that was for Excel 2003 & earlier. These versions of Excel had an internal colour palette of 56 colours. Any colour was assigned to the member of the palette that was closest. So you may be seeing some assignment to an assumed palette. This is only a guess as I do my manipulation of Excel either directly in VBA or via Win32::OLE.
