Social icon facebook visibility

Hello,

I made this website for a costumer (see private content) but the facebook icon is not so visible because it has the same color as the rest of the menu…
Is it possible to place the original facebook logo? Like this one: https://www.iconfinder.com/icons/107175/circle_color_facebook_icon#size=512
So that the blue circle is always visible, not with a mouse-hover.

Thanks in advance!
