Sorry for late response, your simple support question forgotten by our support team. You can change the submenu items in the style.css on line 1451 “background” line.

[code title=””]
ul.sub-menu li {
background: #ffffff;
display: block;
line-height: 26px;
padding: 0;
}[/code]

You can change the main header (logo, main menu container) background color from the theme option panel. Also for forgive ourselves to you, we would like to give one of our themes free!. Please pick up our one of the themes and let us know via email. We’ll send it you you free!

Best Regards
