The Bug

The text in the game pulses between white and blue if it is nighttime and a Wither is nearby, and the player has the Darkness effect. When leaving the game while the text is blue, the blue text will persist across the menus in the game, and will only revert to the white text if the game is restarted, or a different world is logged into.

Steps to Reproduce

Ensure the Darkness Pulsing slider in Accessibility Settings is set to 100%.

1. Set the time to midnight: 

   /time set midnight

2. Summon a Wither: 

   /summon minecraft:wither

3. Give yourself the Darkness effect: 

   /effect give @s minecraft:darkness

4. Note how the text pulses between blue and white text.
5. Exit the world while the text is blue.
6. The main menu's text is all blue. The splash text also looks slightly darker.

Observed Results

While having the Darkness effect at nighttime with a Wither, the text pulses blue. If timed correctly, when exiting the world, the blue text color persists around the game.

Expected Results

This would not happen.
