Dynamically update color of a blog menu icon

Hi.  I've been looking at Example 2 in the advanced documentation regarding modifying the menu for ElggBlog objects http://learn.elgg.org/en/2.3/guides/menus.html  In my case, I'm iterating through a list of individual blog entities and would like to only change the color of the thumbsup icon.  I have a single blog entity already extracted using:

$blog = elgg_extract('entity', $vars, FALSE);

How can I now access the menu icons and change the style color for the thumbsup icon?
