Mobile Menu Colors

Share your site url

Add this CSS to your stylesheet or add it using a plugin:

/* Change #fff to the color you want. */
.wp-block-navigation:not(.has-background) .wp-block-navigation__responsive-container.is-menu-open {
    background-color: #fff;
    color: #000;
}

Is there a way to do it “visually”?

Yes. Click on the navigation block in the full site editor. In the block settings sidebar go to Color > Submenu and overlay background.
