This is not a full GTK theme.
It is simply a CSS modification that makes some GNOME interface elements more transparent.
For example, in the Nautilus file manager, the sidebar will be more transparent than the content area on the right.
If you have used extensions such as Blur my Shell, you probably know that they can add blur effects to application windows.
The problem is that, in order to achieve a blurred background effect, you usually have to increase the transparency of the entire window, including the content inside it.
As a result, text and other UI elements inside the window also become more transparent, reducing the overall contrast and readability of the interface.
With this modification, you don't need to adjust the transparency of the entire window. The window background can be more transparent while the UI elements inside the window remain mostly unaffected.
This makes it possible to achieve more interesting blur effects without sacrificing text contrast and readability.
You can use extensions such as Blur my Shell or Liquid Glass to achieve similar effects.

This modification is not perfect and is not a full GTK theme.
It does not work with all applications and also affects GTK3 applications.
However, you can easily customize it to your needs — just edit the gtk.css file!
