GitHub Pitch Black Theme

A zero-latency, high-performance pitch black theme for GitHub with neutral colors. No JavaScript, no tracking, pure CSS.

Turn GitHub into a true Pitch Black theme — with zero slowdown. Most themes work by running extra code in your browser every time a page loads, which can slow things down or cause a flash of the wrong colors first. This one works differently: it's pure styling, with no code running at all, so the black theme is just there — instantly, every time. FEATURES: 🌑 True Pitch Black — swaps GitHub's dark gray background for pure black. ⚡ Instant — no delay, no flicker, no lag. 🎨 Clean, Neutral Look — softer grays instead of harsh blue tints. 🔋 Battery Friendly — pure black uses less power on OLED phone and laptop screens. Note: your GitHub account also needs to be set to Dark mode — this extension recolors the dark theme, it doesn't turn dark mode on for you. PRIVACY, GUARANTEED: 🔒 No code runs in your browser at all — just colors. There's nothing that could track you, collect your data, or send anything anywhere, even by accident. 🔒 No analytics, no trackers, no background activity of any kind. 🔒 100% open source — anyone can read every line of it, nothing hidden. UNDER THE HOOD: No JavaScript, no background service worker — just a static CSS file declared in `content_scripts` and injected at `document_start`.
