To do that, you will need to modify the functions.php file by taking out these lines of code which contains php code that the theme option settings do. This also means it will render the theme option settings not usable for the colours:
#socialbar .genericon {background-color: ;}
#social-icons a {color: ;}
#social-icons a:hover {color: ;}
Then do custom css to make whatever colour changes you want to the ID’s of each one. The ID styling is found around line 278 in the theme’s style.css file that begins with:
/* Social icons */
