Increasingly, I use color schemes in Excel models as well. While I am about to switch to Microsoft Office 2010, I find that the majority of my clients (especially the large corporate ones) are still on Office 2003. Buried down in the Excel menus is a feature to set the colors that Excel 2003 users will see when they open files created in Excel 2007.
