Inspired by the Arctic night sky and the slow drift of the Northern Lights, this theme blends deep navy and teal shadows with luminous blue and green accents to create a calm yet vivid coding environment. Dark, cool backgrounds keep the editor restful, while bright cyans, fresh greens, and soft lavenders add clarity and energy to key syntax elements.
A dark theme from the Codigrate Nature collection, released 2023-08-13. Tags: Arctic, Cinematic, Luminous.

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.
