Andrew Nevins on "[Theme: Customizr] Changing Colour of Social Media icons in the Footer"

Looks like you've done everything right.

Try this code instead:

.social-block a,
footer#footer .colophon .social-block a { color: #39c6f4; }

.social-block a:hover,
footer#footer .colophon .social-block a:hover { color: #414a9e; }
