IJ Reilly said:Actually, the color-filled box solution will work. Just drag it out the corners of the page. Use Preview to verify. Then define a master page with the colored background page and add that page as many times as you need. Should work fine. The Keynote solution works too, but you'll have to create a custom page size, which could be awkward, depending on what you need.
