Dark Mode: 'Push notifications are turned off' text is unreadable due to low contrast

Expected behavior

I would expect all informational banners within the app to remain readable when dark mode is enabled.

Actual behavior

If push notifications are turned off, a banner related to this is displayed to users on the notifications screen. The text in this banner is unreadable when dark mode is enabled due to low contrast. The text is changed to white, but the banner's background colour remains a light shade.

Steps to reproduce the behavior

• Ensure notification are turned off for the Jetpack app. This can be done via the Apps section in your phone's Settings app.
• Enable dark mode on within the Jetpack by navigating to App Settings → Appearance.
• Navigate to the Notification screen and observe the 'Push notifications are turned off' banner at the top.

Tested on Pixel 6, Android 13, JPAndroid 22.2-rc-2

Start by reproducing the issue on the Notifications screen after disabling notifications and enabling dark mode through App Settings → Appearance. Inspect the implementation of the “Push notifications are turned off” banner and its dark-mode styling; done means the banner text remains readable with sufficient contrast in dark mode without regressing light mode.
