Customising Colour of Social Media Icons

Hi, First up, your search function does not seem to function, no matter what I type I get no matches... so if this question has already been asked and answered i apologise. I would like to change the colour of my social media icons. Is there some custom CSS you can give me or do I need to go into the editor? If so, which line? Thankyou. Sarah - http://thejuiceplanet.com
