If you import an image with a specific color, and then set the background to what appears to be the color, what could happen is that the colors use a different color pallet. There are a couple of things you can do to get around this. The first is to create a very small image (say 5 pixels by 5 pixels) from the same program that you used to create the original image and then use the Page Editor to set that image as the background.

Another thing you can check - select the image, go to the Quick Properties Editor, and try unchecking 're-render'.

The other thing you can do (if the image is a Title) is to try setting the image to a different output - select the image, open the Geometer Editor and change the output to gif.
