At present we have provided only black and white colors for the sociable icons.
If you want to change the size of the icons then follow this path, lifecare/framework/common/sociables.php, find for this code on line around #22 $out .= '<i class="fa fa-'.$sys_social_bookmark_icon[1].' fa-lg" title="'.$sys_social_bookmark_icon[0].'"></i></a></li>'; and you can change here fa-lg to fa-2x, fa-3x etc as you wish.
