Gmail Auto Dark Mode

Gives Gmail a dark theme automatically when your OS is in dark mode. Zero setup, no permissions, real-time switching.

Gmail Auto Dark Mode automatically applies a dark theme to Gmail when your OS is in dark mode, and reverts instantly when you switch back — no buttons, no settings. The goal is simple: make Gmail comfortable to use at night or in low-light environments without any manual effort. Your OS dark mode setting is the only switch you need. It reads your system's color preference in real time, so changing your OS theme updates Gmail immediately without a page reload. Images and videos are counter-inverted to preserve their original appearance. No permissions required. Nothing is read, stored, or transmitted. HOW TO ENABLE DARK MODE - macOS: System Settings → Appearance → Dark - Windows 10/11: Settings → Personalization → Colors → Dark - Ubuntu (GNOME): Settings → Appearance → Dark
