Hello,

Sorry for the late response.

Please edit the file specular/js/main.js. Find this function

function codelessStickyNav(){
	"use strict";
	var opened = false;
	var position = $('.header_wrapper').css('position'); 
	var bool_test = false;
	$('.logo_only_sticky .header_wrapper #logo').css('opacity', 0).css('visibility', 'hidden'); 
	$(window).scroll(function(){
		var top = $(this).scrollTop(); 

		if(top > stickyNavTop + 300 && !opened){
			
			$('body').addClass('sticky_header'); 

			setTimeout(function(){
				if($('.header_wrapper').hasClass('background--dark')){
					$('.header_wrapper').removeClass('background--dark');
					bool_test = true;
				}

Comment out or delete this line:

$('.header_wrapper').removeClass('background--dark');

Best regards!
