How to change color of social icons?

I override the color style of template, but can't understand how to change the color of social icons. I need the green icons instead the blue (see attached image). How can I change color?

This code can overwrite it:

Code: Select all

.gkTeamOverlay a:hover {
    background: #6675e6 none repeat scroll 0 0;
}
