Hi Karl
You can try with this custom css rule and change to your desired color:
/*background color*/
.navbar-default {
background-color: #f254b1;
border-color: #f035a3;
}
.navbar-default .navbar-collapse, .navbar-default .navbar-form {
border-color: #f035a3;
}
/*Text color*/
.navbar-default .navbar-nav > .active > a, .navbar-default .navbar-nav > .active.open > a, .navbar-default .navbar-nav > .active > a:hover, .navbar-default .navbar-nav > .active.open > a:hover, .navbar-default .navbar-nav > .active > a:focus, .navbar-default .navbar-nav > .active.open > a:focus {
color: #ffffff;
background-color: rgba(255,255,255,0.15);
border-radius: 3px;
border-color: transparent;
}
.navbar-default .navbar-nav > li.active + li > a, .navbar-default .navbar-nav > li:first-child > a, .navbar-default .navbar-nav > li.active + li > span, .navbar-default .navbar-nav > li:first-child > span {
border-color: transparent !important;
}
/*Hover color*/
.navbar-default .navbar-nav > .active > a, .navbar-default .navbar-nav > .active.open > a, .navbar-default .navbar-nav > .active > a:hover, .navbar-default .navbar-nav > .active.open > a:hover, .navbar-default .navbar-nav > .active > a:focus, .navbar-default .navbar-nav > .active.open > a:focus {
color: #ffffff;
background-color: rgba(255,255,255,0.15);
