By default, OneNote gives you a blank white canvas to work on. However, if you go to the view menu, you can choose from different paper types.
This will be more useful for different situations, be it inking up a graph, or just taking traditional notes in a lined notebook. By going to view and then choosing Page Colour you can swap out between different page colours. You also can add lines or a grid to your page as well for various types of notebooks, say for graphing or taking actual notes. Just choose the Rule Lines option from the View bar to do this.
