Changing Social Media Icons, Menu hover colors

Hello, I've got a couple of things im trying to edit but struggling to find where the code is to do it. 1. Would like to remove the hover over function for the social media icons so they are constantly filled with their color (normal icons). 2. Change the hover and active colors for the menu, i managed to find the menu bar and change the color for that but cant find the color settings for hover and active. 3. Is there a way of changing the footer color and possibly adding more content into it? like adding links, images. 4. Where the Search Bar was in the header right section (removed on my site from css i found on here) Is it possible to add text or a image in its place?
