How can I change the color of the background or the color of the font for the data displayed?
When you map a request output parameter to a component, there is an option to write JavaScript. In that JavaScript function you are passed two values: value and element. value is the actual value, element is the jQuery Mobile component. As you have a reference to the component, you can set any properties on it, including color.
