Changing link color in Aegeaus

How do I change link colors in Aegeaus? I know where to change it, but I need the correct CSS. Right now, the link color is black like the rest of the text, but turns blue on mouseover.

Also, do you have fuller documentation on how to use the testimonials shortcode? When I apply what is on your site it does not work. For instance, how do I separate the testimonial from the name of the person who gives the testimonial? Do I need to have an opening and a closing declaration? Etc.

By the way, the site is http://www.lightofthespiritpress.com.
