Which items control these background colors?

[spamegg1]

I'm using Catppuccin Mocha Mauve GTK 3.0 theme on the Cinnamon desktop.

I am looking for the lines of code in gtk.css that control these background colors (I think they have something to do with view or selected or hover). They are a bit too indistinct / difficult to see / distinguish for me, I'd like to change them to some shades of pink / purple.

This is the sidebar in a Nemo window (Nemo is the file manager for Cinnamon desktop environment). One line is selected, one is unselected, one has the mouse hovering over it:

This is the sidebar in Geany. One line is selected, one is unselected, one has the mouse hovering over it:

This is from Deluge (a Bittorrent client), here on the right, one line is selected, one is unselected, and one has the mouse hovering over it:

I believe one of them is:

.view:hover {
  box-shadow: inset 0 0 0 9999px alpha(currentColor, 0.08);
}

and another one (for mouse hovering over it) is:

menu menuitem:hover,
.menu menuitem:hover,
.context-menu menuitem:hover {
  background-color: alpha(currentColor, 0.08);
}

Are these right?
Which one controls the selected line?
