How can I make the latest Firefox use the Default Theme (Tab Color) from Firefox 75?

I really like the look of the default tab color in Firefox 75. I'm currently running FF 95.0.2 on a Windows 10 machine (64-bit) and would like to customize this browser to have the look of FF75. I've seen some posts on different add-on themes to change the tab color but still am not sure how to make the changes. I would think that maybe there is an about:config way to go about this. The color I'm looking for, looks to my eyes like a deep navy blue or deep purple. Attached is a pic. Please let me know how I can go about getting the tab color with the visible 'breaks' which separate one tab from another.

Thanks, backspin11

For tab colours your options are a theme or userChrome.css. You can use the latter to create visible separators between tabs and a theme may do that also.
