}Get this theme
The commands below are macOS-only (custom-image themes are macOS-exclusive). Windows currently supports only the built-in fixed skin — see the Windows section of the tutorial. Both methods run locally and restore in one click.
Copy apply command (recommended)
Copy and run — it auto-downloads this theme's matching background to ~/Downloads, generates theme.json, and auto-applies (edit the image path in the command to use your own).
Download theme.json pack
Download theme.json and put it in one folder with your background image (renamed background.jpg).
For option 2, drop the folder into the theme library, then switch:
~/.codex/codex-dream-skin-studio/scripts/switch-theme-macos.sh --id codex-nord-themeLibrary path: ~/Library/Application Support/CodexDreamSkinStudio/themes/codex-nord-theme/ (needs theme.json + background.jpg). Hot-switches if Codex is open; otherwise double-click Start.

Overview
Nord is inspired by the polar night and ice of the Arctic — a scheme known for being restrained and easy on the eyes. It has no harsh neon, just blue-gray polar-night tones accented by a touch of frost blue. It's gentle during long Codex sessions and suits people who like a calm, professional, unflashy look — the default choice for many senior developers.
Palette breakdown
The background #2E3440 is Nord's polar-night blue-gray; panels #3B4252 and the sidebar #292E39 add depth. The primary #88C0D0 (frost cyan) and secondary #5E81AC (frost blue) are Nord's signature Frost colors, used for accents and active states. Body text #D8DEE9 is snow-white, muted text #7B8398 slate. Syntax highlighting is restrained: keywords #81A1C1, strings #A3BE8C sage, comments #616E88 understated.
How to apply
On macOS, use the Customize command with a cool-toned background and Nord's frost colors: customize-theme-macos.sh --image bg.png --name "Nord" --accent "#88c0d0" --secondary "#5e81ac" --highlight "#81a1c1". It auto-applies via local CDP (127.0.0.1:9341) once generated.

Before you use it
Theme previews on this page are illustrative; actual results depend on your local setup. Theming works via local CDP (Chrome DevTools Protocol) CSS/JS injection — an unofficial approach that never modifies the official Codex bundle or code signature, but a Codex version update may briefly break the skin. If it breaks, run the open-source Restore script to revert, or wait for the engine to update. Please use it in line with Codex's terms of service.
