Within the C:program filesMicrosoft OfficeDocument Themes 12 folder I opened the 'module.thmx' file and edited the 'theme1.thmx' file to include custom colors. It worked. I double click on Module.thmx, which launches ppt and see my custom colors on the color palette. However, if I launch ppt straight away I do not see my custom colors. My question: How do I see my 'custom colors' in PPT, Word and Excel? Do I have to store this 'module.thmx' in another location?
