Header colour

Hi,
To resolve this issue, you can add the following code to the style.css file:

.navbar-inverse .navbar-inner { background: #fff !important; }
.navbar .nav { background: #fff !important; }
.navbar .nav>li>a { color: #000 !important; }
.navbar .nav > [class*="icon-"]:before { color: #000 !important; }
.navbar .nav > li[class*="icon"]:hover:before, .navbar .nav > li[class*="icon"]:focus:before, .navbar .nav li[class*="current"][class*="icon"]:before { color: #ff4629 !important; }
.navbar-inverse .brand:hover, .navbar-inverse .nav > li > a:hover, .navbar-inverse .brand:focus, .navbar-inverse .nav > li > a:focus { color: #fff !important; }

Hope this helps !
