Email Us Hover

I seem to have set the same color for my top header and footer as the hover color, but I can’t figure out where. So when you hover over the social icons at the top they disappear. I was able to fix this problem on the top header by using the following css:
#header-bar a:hover {
color: #a4c639 !important;
}

I can’t seem to get the same to work for the Email Us link at the bottom. I have tried both of the following:
#text-2 a:hover {
color: #a4c639 !important;
}
OR
#footer a:hover {
color: #a4c639 !important;
}
