Tyrian Night
A deep, ultra-saturated dark theme built on color science. Maximum depth and saturation within WCAG AA compliance.
Features
- WCAG AA compliant — 12:1 main text contrast (AAA), 4.5–7:1 for all syntax tokens
- Perceptually distinct colors — every syntax category separated by CIEDE2000 ΔE > 12
- True dark background —
#0C0C0C canvas, optimized for OLED and dim environments
- Full semantic highlighting — declared natively in the theme, no configuration needed
- Universal language support — Works with any language using TextMate grammars (JavaScript, Python, Rust, Go, etc.)
- Optional Island UI layout — rounded panels via Custom UI Style, consent-prompted on first run
Installation
- Extensions panel → search
Tyrian Night → Install
- Ctrl+K Ctrl+T → select Tyrian Night
Island UI Layout (Optional)
Tyrian Night ships a CSS stylesheet for rounded, floating panels. It requires the Custom UI Style extension.
- Install Custom UI Style
- Reload — Tyrian Night will prompt to enable the Island layout
- Accept and reload again to apply
Decline the prompt to use the theme without layout modifications. The choice is stored and won't ask again.
