Immutable Theme
The last VS Code theme you'll ever install.
A calm, elegant dark theme built for developers who are done theme-hopping —
no neon bursts, no color overload. Just clean, focused code.

Python — FastAPI service
JavaScript — Async task queue
Why Immutable?
Most themes get swapped out within a week. Immutable was designed so you never feel that itch.
- Consistent elevation system — backgrounds follow a strict 5-tier depth scale so the UI hierarchy is always clear, never accidental.
- Semantic token coverage — TypeScript, Python, Rust, Go, Java, and C# all get hand-tuned colors, not just TextMate fallbacks.
- Every surface themed — autocomplete widgets, inlay hints, diff views, merge conflicts, git decorations, notifications — nothing falls back to VS Code defaults.
- Two depths, one identity — pick the variant that suits your monitor and lighting. Both feel like the same theme.
