When I click a post title, it turns to black. How can I change this?

Hey, So im wondering as i described in the title how i would would go about changing this… I inspected it with firebug and i did change the CSS a bit, but still nothing…

My blog theme is Easel. It has a dark background so once i click on a certain post to get the URL for it, the post title turns black, making it nearly impossible to read. I will post an example below
