IOS 16 Lock Screen

Hello Bugslc,

Thank you for reaching out to Apple Support Communities.

Have you tried customizing the clock color itself? These steps may help:

"Create a custom Lock Screen

1. Touch and hold the Lock Screen until the Customize button appears at the bottom of the screen.If the Customize button doesn’t appear, touch and hold the Lock Screen again, then enter your passcode.
2. Tap  at the bottom of the screen.The Lock Screen wallpaper gallery appears.
3. Tap one of the wallpaper options to select it as your Lock Screen.For some wallpaper choices, you can swipe left or right to try different color filters, patterns, and fonts that complement each other.
4. Tap Add, then do one of the following:

• Choose whether to use the wallpaper on both the Lock Screen and Home Screen: Tap Set as Wallpaper Pair.
• Make further changes to the Home Screen: Tap Customize Home Screen. Tap a color to change the wallpaper color, tap  to use a custom photo, or select Blur to blur the wallpaper so the apps stand out."

If the issue persists, can you provide a few more details? What is your exact iOS version? What happens when you attempt to customize the color of the clock? Also, does this happen with multiple lock screens?

Cheers!
