Give color targets the ability to display each LCD line a different color and use this newfangled ability to provide themable colored file types. See the comments on read_color_theme_file and the sample.colors file provided for how to use this. .colors files go in themes directory for now. This separate line color function should be trivial to add to menus and wpss.
