Hi there, I'm desperately trying to change the header background colour on the shop page black to match the other pages so that you can see the logo. Any help would be appreciated! 

Add to Design > Custom CSS

body[class*="type-products"] header#header img {
    filter: invert(1);
    -webkit-filter: invert(1);
}
