Dynamic Header Needed

Site URL: https://globaldirectpartners.com/

I need my menu and header graphic logo to change on certain pages where the graphic under them moves from light to dark. 
 

the light logo and white menu looks great when on a dark surface. But when the underlying graphic is a light colored image it disappears. 
 

how can I get the menu colors and the logo version to change by page color? What code is needed?

Thank you 

You can add this code to Page Header (page where you have problem)

<style>
  header#header img {
  	content: url(https://cdn.pixabay.com/photo/2022/06/07/03/25/rice-fields-7247360__340.jpg);
  }
      div.header-nav-item a {
    	color: black !important;
    }
</style>

Replace with new logo image url.
