you could try getting a background image that suits you and drag it onto the onenote page, create a new page first.
drag the corner to resize it large
then right click the picture when you have filled the box , (it takes a short while ) then select set as a background,
then click file and page set up and at the bottom click save page as a template,
now we need to work out how to change the automatic text color to white,
this is it so far ,
