Da ich Thunderbird komplett an meinen Wünschen angepasst habe, werden bei mir diese Farben wohl ausgeblendet.
Ich habe mal ein wenig getüftelt, teste mal das ↓ in der userChrome.css.

P.S.:
Für Wiederkehrende Aufgaben habe ich allerdings noch keine Lösung, da bin ich noch am Suchen.
PP.S.:
Die Farben sind allerdings von kopierten Einträgen und passen noch nicht wirklich, die musst Du noch anpassen.
