Hi @smezstudios 

- Go to Online Store -> Theme -> Edit code.
- Find the file Layouts/theme.liquid and paste the code below at the bottom of the file."

{% if template.name == 'index' %}
<style>
.header__heading-link.link.link--text.focus-inset {
background: black;
}
</style>
{% endif%}

hi unfortunately that did not work at all and is not what im after. 

I want the logo to stay exactly the same on the homepage like so.

but on my other pages the logo to be black- as you can see right now it is not showing up. I think its because i have coded in a transparent header for the home page
