Apply CSS to jQuery Dialog Buttons

So I currently have a jQuery dialog with two buttons: Save and Close. I create the dialog using the code below:

$dialogDiv.dialog({
    autoOpen: false,
    modal: true,
    width: 600,
    resizable: false,
    buttons: {
        Cancel: function() {
                        // Cancel code here
        },
        'Save': function() {
                        // Save code here
        }
    },
    close: function() {
        // Close code here (incidentally, same as Cancel code)
    }
});

However, both buttons are the same color when this code is used. I'd like my Cancel button to be a different color than my Save. Is there a way to do this using some built in jQuery options? I didn't get much help from the documentation.

Note that the Cancel button I'm creating is a pre-defined type, but 'Save' I'm defining myself. Not sure if that will have any bearing on the issue.

Any help would be appreciated. Thanks.

UPDATE: Consensus was that there were two roads to travel here:

1. Inspect the HTML using a Firefox plugin like firebug, and note the CSS classes that jQuery is applying to the buttons, and take a stab at overriding them. Note: in my HTML, both buttons were used the exact same CSS classes and no unique IDs, so this option was out.
2. Use a jQuery selector on dialog open to catch the button that I wanted, and add a CSS class to it then.

I went with the second option, and used the jQuery find() method as I think this is more appropriate than using :first or :first-child b/c the button that I wanted to change wasn't necessarily the first button listed in the markup. Using find, I can just specify the name of the button, and add CSS that way. The code I ended up with is below:

$dialogDiv.dialog({
    autoOpen: false,
    modal: true,
    width: 600,
    resizable: false,
    button
