Dark Icon Feature Box Titles

Hello

The titles of my icon feature boxes are barely visible on my black background. How can I make them white. You can see the page here: http://www.localmarketingdominance.com/landing-page/

Also, how is it possible to change the font of a page and use several different font types as in this page of the theme demo: http://hb-themes.com/themes/highend_wp/home-special-dark/

Thank you.
