How to Change Custom Nav Link Color in Footer

I want to change my footer navigation menu link color to white.

I have been successful in changing the header text & link color, along with the "email" text in the footer, but I am unable to change the grey custom menu links in the footer.

Please visit that link and scroll to the bottom in the footer on the left hand side corner next to the email subscribe form.

I believe I need to change the menu nav links but I tried that with no success.
