WordPress – can not seem to change footer-menu hover color

Hello, I have been trying to get the footer menu on my site to change to #46B450 when you over over it and to show as #46B450 when you are on the page. Just like the top menu does. I have been working on this for 1.5 hours straight, following multiple different instructions on line but none of the code seems to be working. Can someone please help me? Here is my site: www.wepracticesafe.com Thank you.
