Nothing is exposed to do that at the moment in Readium. There is a way to do it with Readium CSS by overriding the --USER__backgroundColor and --USER__textColor CSS variables, but it's not easy to do if you are just getting started with the Readium Toolkit. Font faces cannot be added either without modifying the toolkit, or injecting manually the CSS in the web views.
