Awesome Codex Themes

A curated list of themes, skins, galleries, and theming tools for OpenAI Codex — the Codex CLI, the Codex desktop app, and the Codex IDE extension.

Codex theming happens on three surfaces:

1. Codex CLI (terminal TUI) — 32 bundled syntax themes, switched with the /theme slash command (live preview) or tui.theme = "..." in ~/.codex/config.toml. Custom themes are standard TextMate .tmTheme files dropped into $CODEX_HOME/themes/ — thousands of existing Sublime Text / TextMate color schemes work out of the box.
2. Codex desktop app — full appearance customization (base theme, accent/ink/surface colors, fonts, semantic diff colors) shipped in late March 2026. Themes travel as portable codex-theme-v1:{...} JSON strings, imported via Settings → Appearance → Dark/Light Theme → Import.
3. Skins (CDP injection) — community tools inject CSS/artwork into the Codex desktop app at runtime over the local Chrome DevTools Protocol, enabling wallpaper-level customization far beyond color themes, without patching official binaries.

Official Resources

• openai/codex — The official Codex CLI repository; TUI theming lives in codex-rs/tui.
• Codex Config Reference — Official config.toml reference, including tui.theme and tui.status_line.
• Codex App Settings — Official docs for the desktop app's appearance settings.
• Codex TUI Style Guide — The color/style conventions the Codex TUI itself follows.

How Theming Works

CLI: .tmTheme + config.toml

# ~/.codex/config.toml
[tui]
theme = "catppuccin-mocha"   # any bundled name, or a custom .tmTheme in ~/.codex/themes/

Type /theme inside Codex for a live-preview picker that persists your choice. Custom themes are plain TextMate .tmTheme files: place my-theme.tmTheme in ~/.codex/themes/ and set theme = "my-theme" (the kebab-case filename becomes the theme name).

The CLI bundles 32 themes (defaults: catppuccin-mocha on dark terminals, catppuccin-latte on light):

Family	Theme names
Catppuccin	catppuccin-mocha · catppuccin-latte · catppuccin-frappe · catppuccin-macchiato
Base16	base16 · base16-256 · base16-eighties-dark · base16-mocha-dark · base16-ocean-dark · base16-ocean-light
Monokai Extended	monokai-extended · monokai-extended-bright · monokai-extended-light · monokai-extended-origin
Gruvbox	gruvbox-dark · gruvbox-light
Solarized	solarized-dark · solarized-light
One / Two	one-half-dark · one-half-light · two-dark
Coldark	coldark-cold · coldark-dark
GitHub	github · inspired-github
Classics	dracula · nord · zenburn · sublime-snazzy · dark-neon · 1337 · ansi

App: codex-theme-v1 import strings

Desktop app themes are JSON payloads prefixed with codex-theme-v1:. Fields include codeThemeId, theme.accent, theme.ink (text), theme.surface (background), theme.contrast, theme.opaqueWindows, theme.fonts.{ui,code}, theme.semanticColors.{diffAdded,diffRemoved,skill}, and variant (dark/light). Import via Settings → Appearance → Dark/Light Theme → Import.

Gotcha: codeThemeId must match a built-in id (tokyo-night, one-dark, nord, dracula, catppuccin, gruvbox, solarized, github-light, matrix, one) — unknown ids fail silently (openai/codex#14766). Theme authors work around this by reusing a built-in id and overriding all colors.

The app ships built-in classics (Catppuccin, Monokai, Solarized) plus official partner themes including Linear, Notion, Raycast, and OpenClaw.

Codex CLI Themes

• ychampion/codex-themes — Open-source theme manager for Codex CLI: validates community themes, previews in the terminal, installs .tmTheme files, writes reversible config.toml, ships status-line presets, and exports matching palettes for Windows Terminal, iTerm2, Ghostty, and Alacritty. MIT

• Any .tmTheme collection works too — e.g. the hundreds of schemes bundled with bat or from TextMate/Sublime theme galleries; drop the file into ~/.codex/themes/.
