iOS 13 Dark Mode Blue Action Buttons Need To Lighten Up

Loving Dark Mode in iOS 13, but the blue action buttons against black background are REALLY hard to read. In apps like Notes, the buttons (all iCloud, add, share, done, 2019, search, add, Today, Calendars, Inbox)) are yellow and easy to read, as are Calendar with red text. App Store, Mail, Reminders, Photos (without setting to max brightness) would benefit with lighter text. What are the chances of this happening?
