Hello,

I have changed the logo for the header that was used for the shop page as a custom header.

Screenshot for Clarification: UNDER PRIVATE CONTENT AREA

And for the product’s names color, cart, and checkout button background try adding the following Custom CSS in the Global Custom CSS area under Theme Settings.

.elementor-menu-cart__product-name.product-name a {
	color: white;
}

a.elementor-button.elementor-button--view-cart.elementor-size-md {
	background: #4d7abd;
	color: white;
}

a.elementor-button.elementor-button--checkout.elementor-size-md {
	background: #4d7abd;
	color: white;
}

Regard’s.
