in your html,

<button class="button" id="redButton" /> Red </button>
<button class="button" id="blueButton" /> Blue </button>
<button class="button" id="greenButton" /> Green </button>

in your js file,

$(document).ready(function(){

$('#redButton').click(function() {
    $('body').css('background-color', '#FF0000');
});

$('#greenButton').click(function() {
    $('body').css('background-color', '#00FF00');
});

$('#blueButton').click(function() {
    $('body').css('background-color', '#0000FF');
}); 

});
