Home Page Right Feature Widget Area - Change Text color and font to match theme?

I am using the Home Page Right Feature Widget Area instead of the Lead Capture Form. The text color and font does not match the rest of the site. Can you please reply with the CSS to make the text color and font match the rest of the theme?
