hello Racheal,

I am really sorry for the delay of this reply as it is a weekend for us here.
Actually you no need modify the css file from Easyblog, you can apply this css code in your template css file that was better in your future if you update the Easyblog.

/*blog title link*/

#ezblog-body .blog-post .blog-title, 

#ezblog-body .blog-post .blog-title a {

  color: red !important;

}



/*category link*/

#ezblog-body .blog-category a{

   color: blue !important;

}

By the way, I listed the code above is just under the blog tittle link and category link, if you would like all the link modify to same color, you can using this css.

#ezblog-body a {

  color: red !important;

}

Hope this help.
