You can change the color using CSS. You will want to make a child theme, or use a custom CSS plugin though (otherwise your changes will be lost when you update).

It looks like the code for the blue is

.nav li.current-menu-item > a, .nav li.current-menu-parent > a {
  color: #fff;
  text-shadow: none;
  background-color: #428bca;
}

If you use a custom CSS plugin, you should be able to just copy and paste that code. You can then change the value where it says background-color to what ever hex-value you’d like.

Could you post a link to your site? It is possible to change the colors of the links using CSS (you will need to use a child theme or custom css plugin though or your changes will be lost if you update the theme).

As far as the icons go, it will matter if they are pure css icons or images.

It looks like you are not using a child theme. You can make the changes you want through css, but you’ll want to use a custom css plugin or create a child theme. If you make css changes to the core files they will be overwritten if you update the theme.

You’ve left your #main open. The bottom of your stylesheet should look like this. Of course keeping #sidebar as is.

#main
{
	background:#FFF;
}
#header-menu li.menu-item a:hover {
	color: #05F475;
}
#nav_menu-2 a:hover {
	color: #05F475;
}

http://codex.wordpress.org/Themes I think this should help.

#header-menu li.menu-item a:hover {
	color: green;
}

You’ll need to replace green with the hex value for the actual color green you want to use.

Edit: If you want the sidebar menu to hover green as well you can use

#nav_menu-2 a:hover {
	color: green;
}

for that.

Could you please post a link to the site/page?
