Hey there anice06,
How are you doing today?
You should be able to change your header color with some custom CSS. To do please try adding the following CSS code in the style.css file of your child theme or add it in your site using the following plugin:
https://www.ads-software.com/plugins/simple-custom-css that please
div#main-nav.navbar {
background: #fff;
}
This is the original background color of the top bar and to change it you’ll have to replace color hex value (#fff). You can use sites similar to this one to get hex value for the color of your choice: https://www.color-hex.com/.
Also please note that your logo image has white background instead of transparent one so changing this will leave white square around the logo.
Hope this helps ??
Best regards,
Bojan
