Is your link color boring or not noticeable? You can change it pretty easily, and here's how.

Note: I forgot to mention in the video that if you do not have a child theme installed (common with free themes), updating your theme will probably erase any code changes you make. You can just change it again after the update.

If you have a premium theme with a framework (like Genesis or Thesis), be sure to make the changes you made are to the CHILD theme.
