Gboard Material Expressive Black

LSPosed module that restores pitch black backgrounds to Gboard on Android 16, bypassing Material 3 Expressive enforcement while preserving dynamic theme colors.

Why This Module?

Starting with Android 16 and Material 3 Expressive, Gboard enforces tinted grey surface colors instead of pitch black. This design change breaks AMOLED power savings and prevents pure black themes.

This module intercepts Material You color lookups at the system level using LSPosed hooks, replacing surface container colors with pitch black while preserving wallpaper-derived dynamic theme colors.
