Can't change colour of social icons in socket

hi guys

I can’t understand where the social icons in my socket have got a strange colour from i haven’t specified in the theme settings at all, the website socket is http://www.apollonia-dcc.com/

I’ve tried putting this into the theme quick css settings but it made no difference

.main_color .social_bookmarks a{
color:white!important;
}

any feedback much appreciated. From looking at the developer console it appears its coming from the dynamic css but i can’t see this setting anywhere in the appearence and id never pick such a dull colour
