Social Media Icons – They ARE there, but you can't see them

Hello! First of all I want to thank you for this wonderful theme, I really love it. I am really new on this and I am trying to do my best with all the help I can find in Google. But I have this problem with the social media icons. They are in the site, but you can’t see them unless you hover them. So, of course, I know they are there, but no visitor is going to find them. What am I doing wrong?

I have no content yet, because I’m still trying to customize the theme. I posted some random things just to see how they look.

Thanks,

Carina
