Hi,
So i'm new to open core. I'm running the latest 0.6.3... I been a clover user for years, i would revert back to clover if i could but it doesn't work well with big sur so here i am.. How do i change the gui theme background? Default is black, i would like to customize it, possibly if i can the same way i did with clover...

If I understand your post I think you're referring to how mine is depicted here in these pics. The process is easy if a bit long winded so have a look at my examples. All changes must be reflected in the config.plist as well as the Resources Folder residing in the EFI Folder. By posting my EFI Folder (all personal Data removed) you maybe able to get an idea of what is needed to achieve the 'Clover-like' results you want.
