Reply To: Help with header area

That background color is coming from the #head-wrap, so you’d need to remove it from the other code –

.epik-blue #head-wrap, 
.epik-blue #welcome, 
.epik-blue #home-feature-bg-dark, 
.epik-blue .author-box, 
.epik-blue .footer-widgets {
    background: none repeat scroll 0 0 #1887e5;
    color: #ddd;
}

Although the new version of Epik makes this easier to do….but don’t do the automatic upgrade if you’ve made a lot of css customizations.
