Nocturne – Oled Dark Mode

**Nocturne – OLED Dark Mode** gives you a true black browsing experience, perfectly tuned for OLED screens. It applies a deep, energy‑saving dark theme to any website while keeping images, videos, and other media untouched.

### ✨ Features

- **Pure OLED black backgrounds** – uses a contrast filter to achieve rich blacks without ugly gray tones.
- **Media preserved** – images, videos, SVGs, canvases, and iframes remain unchanged. No more inverted pictures.
- **Per‑site toggle** – disable dark mode on specific sites with a single click. Your preferences are saved.
- **Adjustable contrast** – fine‑tune the darkness from 1.0 (standard) to 1.5 (extra punch) to match your eyes.
- **Auto‑refresh option** – when you change contrast, the page can reload instantly, or you can choose a manual refresh button.
- **Lightweight & fast** – runs at page start, no flickering. Minimal permissions, no tracking.

### 🖥️ How it works

The extension adds a subtle contrast filter to the whole page, turning backgrounds black and text white. It then removes the effect from images, videos, and other media so they appear normally. All settings are stored locally and sync across your devices if you’re signed in to Chrome.

### 💡 Why Nocturne?

Most dark‑mode extensions invert colors, which looks terrible on images and videos. Nocturne was built from the ground up for OLED displays and respects your media. Whether you're reading, coding, or watching videos, your eyes will thank you.
