changed some code in social-buttons.php:
this works, but not red:
<?php
if (!empty($evolve_googleplus)) { ?>
<li><a target="_blank" href="<?php if ($evolve_googleplus != "" ) echo $evolve_googleplus; ?>" class="tipsytext" id="googleplus" original-title="<?php _e( 'Google Plus', 'evolve' ); ?>"><i class="t4p-icon-social-google-plus"></i></a></li><?php } else { ?><?php } ?>
But now I only have a grey Google+ icon while the rest of the icons are red.
