Tyrian Night
A deep, ultra-saturated theme family built on color science. Main editor text and syntax colors are tuned for WCAG AA contrast while quieter UI chrome stays intentionally lower contrast.
Features
- WCAG AA tuned across the family — Night, Dusk, and Dawn keep AAA main text and AA syntax contrast
- Perceptually distinct core palette — advertised syntax roles are separated by CIEDE2000 ΔE > 12
- True dark background —
#0C0C0C canvas, optimized for OLED and dim environments
- Full semantic highlighting — declared natively, no configuration needed
- Universal language support — works with any TextMate grammar
- Built-in Island UI controls — apply, repair, and restore the workbench patch without

Island UI
Tyrian Night ships its own Island UI installer — no external UI patching extension required.
When a Tyrian theme is active, the extension can install or repair Island UI. Switching away from the Tyrian theme family restores the stock VS Code shell.
[!WARNING]
If Island UI is active, you must run Tyrian Night: Restore Classic UI before uninstalling the extension. Uninstalling Tyrian Night does not remove the custom UI patch.
[!WARNING]
Do not click uninstall first. Restore the classic UI, reload VS Code, confirm the patch is gone, and only then uninstall the extension.
The patch surface is intentionally narrow: a single Tyrian stylesheet injected into workbench.html, one CSS asset copied into the workbench directory, and a matching product.json checksum update. Tyrian-owned backups sit next to patched files for reliable rollback, and a small user-level registry tracks managed app roots so Restore Classic UI can clean up completely.
Required uninstall steps:
- Run
Tyrian Night: Restore Classic UI.
- Reload VS Code.
- Confirm the custom UI is gone.
- Uninstall the extension.
Commands:
Tyrian Night: Apply Island UI · Repair Island UI · Restore Classic UI · Doctor Island UI
Doctor classifies each managed app root as clean, patched, managed-only, permission-denied, broken-backup, or checksum-mismatch, and offers automatic repair when it finds self-healable state.
Because Island UI patches workbench.html, VS Code may show "Your installation appears to be corrupt" while it is active. This is expected and does not indicate broken files.
