Hyperlink Colors Showing Different Colors

Hi. How do I change the color of our hyperlink colors? I have put in the additional CSS in the Customize section – a:link {color:#3d92fe; text-decoration:none;}

This sometimes does one color blue and other links does another color blue. Here is an example…..http://www.surfyogamaui.com/wedding-surf-parties/

When I am logged in to my account…and can see the backend sidebar widget areas….or the (edit) buttons…..they display a different color blue.

Thank you in advance for the assistance on where this can be updated so all our links on the whole site are just one color.
