Looking more closely the alternating colours are all in Tables/TreeViews, etc.

From snooping in the Sigil code, I see the following:

Kevins-MacBook-Pro:Sigil kbhend$ grep setAlternatingRowColors `find ./ -name "*.cpp"`
.//src/Dialogs/ClipEditor.cpp:    ui.ClipEditorTree->setAlternatingRowColors(true);
.//src/Dialogs/DeleteFiles.cpp:    ui.Table->setAlternatingRowColors(true);
.//src/Dialogs/DeleteStyles.cpp:    ui.Table->setAlternatingRowColors(true);
.//src/Dialogs/IndexEditor.cpp:    ui.IndexEditorTree->setAlternatingRowColors(true);
.//src/Dialogs/PreferenceWidgets/SpellCheckWidget.cpp:    ui.userDictList->setAlternatingRowColors(true);
.//src/Dialogs/SearchEditor.cpp:    ui.SearchEditorTree->setAlternatingRowColors(true);
.//src/Dialogs/SpellcheckEditor.cpp:    ui.SpellcheckEditorTree->setAlternatingRowColors(true);

This is not new. The Sigil code has always used these settings.

In a stylesheet you should look to change or add the "alternate-background-color" property for QTableView, QTableWidget, QTreeView, and QTreeWidget.

See https://doc.qt.io/qt-5/stylesheet-reference.html for more details.

Hope this helps.
