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.

1

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).

2

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-monokai-theme

Library path: ~/Library/Application Support/CodexDreamSkinStudio/themes/codex-monokai-theme/ (needs theme.json + background.jpg). Hot-switches if Codex is open; otherwise double-click Start.

Overview

Monokai is practically synonymous with code-editor color schemes — popular from the TextMate and Sublime Text era right through today. Its signature is the high-contrast combo of pink keywords against green strings, instantly recognizable among dark themes. This Codex version keeps Monokai's warm deep base and signature syntax colors — perfect for nostalgic veteran developers.

Palette breakdown

The background #272822 is Monokai's signature warm brownish-green, with code blocks a shade deeper at #1E1F1C. The primary #F92672 (pink) drives keywords and accents, the secondary #66D9EF (cyan) marks function names. The syntax colors are its soul: strings #E6DB74 warm yellow, comments #75715E gray-brown, keywords pink, functions cyan — high contrast yet harmonious. Body text #F8F8F2 is near-white.

How to apply

On macOS, use the Customize command with a background image and Monokai's pink-cyan colors: customize-theme-macos.sh --image bg.png --name "Monokai" --accent "#f92672" --secondary "#66d9ef" --highlight "#a6e22e". It auto-applies via local CDP 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.
