GTK3?

grep -C3 "treeview.view.selected" .config/gtk-3.0/gtk-default.css
    -GtkTreeView-tree-line-width: 1;
    -GtkTreeView-tree-line-pattern: '';
    -GtkTreeView-expander-size: 16; }
  treeview.view:selected:focus, treeview.view:selected {
    border-radius: 0; }
  treeview.view:selected:backdrop, treeview.view:selected {
    border-left-color: #a5c8ec;
    border-top-color: rgba(46, 52, 54, 0.1); }
  treeview.view:disabled {

I assume that after changing complete background, you have to set
background for selected again. Above #4a90d9 looks like that color. You
have to find out how to do it exactly yourself.
