Styling the controlgroup buttons in Jquery Mobile - jquery-mobile

Question

I have a controlgroup with grouping 3 radio buttons to look like buttons, and what I want to do is to to colour the button on click of each one. Clicking the "Red" will change the colour of the button to "Red"
The code is below
<div data-role="fieldcontain">
<fieldset data-role="controlgroup" data-type="horizontal">
<input type="radio" name="rd1" id="rd1" value="R" />
<label for="rd1">Red</label>
<input type="radio" name="rd2" id="rd2" value="G" />
<label for="rd2">Green</label>
<input type="radio" name="rd3" id="rd3" value="B" />
<label for="rd3">Blue</label>
</fieldset>
Can somebody please help me on this.
