Apologies.  It's Themes > Header.

can you call out the code you change.  All I found that seemed to do anything was this in the CSS.

.navbar-inverse .navbar-toggle {
border-color: rgba(255, 255, 255, 0.25);
}

And  when I changed that all it did was seem to highlight the menu boarder in another color. So it kind of looked like more original screenshot.

Sure.  It's the second line in the html.  <nav class="navbar-inverse">

Change the class from navbar-inverse to navbar-default.
