Font color change; theme wide for posts

Hey guys,

On my current site, projectroto.com, the text is fairly light on all of the post (here is an example - http://projectroto.com/the-daily-turnover-feb-21/) or even on the home page. I looked through the theme options but did not see anything to make a color adjustment site/theme wide. I have already reached out to the theme dev but thought I would hit you guys up as well.

Thanks as always!
