Category List – Alternating Rows

I am creating a page that list all my categories. How can I create a list of alternating row colors when the list generates? It would also be great for the row to change color when a user hovers over it.

This is the code I am using the generate the category list

<?php wp_list_categories(‘orderby=name&title_li’);?>

I am a relative newbie so please answer with as much specifics as possible. Thanks everyone.
