Inspired by Mount Etna's nighttime eruptions, this dark theme builds on an ashen basalt grey base and layers in the incandescent reds, oranges, and golds of molten lava. The near-neutral charcoal surface keeps long sessions calm, while the warm lava accents draw the eye to what matters.
A dark theme from the Codigrate Nature collection, released 2026-06-28. Tags: Ember, Earthy, Cinematic.

Getting started on Claude Code
- Download the theme with the Download button. It is one file named after the theme, for example codigrate-london.json; keep the name as is.
- Move the file into your Claude Code themes folder, ~/.claude/themes/. If the folder is not there yet, create it in a terminal: mkdir -p ~/.claude/themes
- In Claude Code, type /theme and pick the theme from the list, for example Codigrate London. It applies at once.
- For the best result, install the same theme for your terminal too ( Ghostty, iTerm2 or macOS Terminal ): Claude Code colors code with your terminal's colors, so with the matching terminal theme the code reads like the theme in your IDE.

From the blog
- Anatomy of a Dark Theme: Etna: Anatomy of Etna, a dark IDE theme: basalt and volcanic ash for the frame, lava rose keywords, sulfur gold members and strings the grey of fresh ash.
- Value: How Colors Get Vivid: Value is the V in HSV, the brightness dial that tops out at the pure color, not white. How it differs from lightness, and why designers reach for it.
