Get this theme

Pick either — both run locally and restore in one click (macOS only; Windows supports just the built-in fixed skin — see the tutorial).

Copy the prompt below, paste it into Codex or Claude, and send. The AI clones & installs Codex Dream Skin, downloads this theme's matching background, generates the theme with its palette, and applies it.

Use the open-source Codex Dream Skin project to install the Codex theming tool and apply the "Nord Theme" theme:

1. Clone & install: https://github.com/Fei-Away/Codex-Dream-Skin (macOS reuses Codex's bundled Node; Windows needs Node.js 22+)
2. Download the matching background: https://codexskins.art/themes/codex-nord-theme.png
3. Generate the theme with it, colors: accent #88c0d0, secondary #5e81ac, highlight #88c0d0
4. Apply to Codex; tune colors if any text is unreadable

If the engine isn't installed yet, install it per the repo README first; run Restore to revert if anything goes wrong.

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.

FAQ for this theme

Is Nord easy on the eyes?

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.
