You will have to open your template for editing and make the change there. If you are not intentionally using a template, your documents are based on Normal.dotm. You can open that template for editing by using the following VBA trick: In Word, press Alt+F11 (or Alt+Fn+F11 on some keyboards) to display the Visual Basic Editor. Press Ctrl+G to activate the Immediate window. Type NormalTemplate.OpenAsDocument and press Enter. Normal will open in a separate window and you can change the page color. Save and close the file. Restart Word.
