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 "Galaxy 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-galaxy-theme.png
3. Generate the theme with it, colors: accent #a855f7, secondary #4f8ff7, highlight #a855f7
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.Color palette
The core palette for this theme. Every control — sidebar, input box, suggestion card, code block — uses these colors.

Overview
The Galaxy theme brings cosmic deep space into Codex: over a near-black deep-purple base, purple and blue intertwine like nebulae. The mood is immersive, mysterious and romantic — for those who love the cosmos and want a workspace with a sense of story. Pair it with a nebula or starry background, and late-night coding feels like drifting through the Milky Way.
Palette breakdown
The background #0A0820 is deep-space near-black purple; panels #141030 are slightly lighter. The primary #A855F7 nebula purple drives accents, the secondary #4F8FF7 starlight blue accents them — the purple-blue interplay is the soul of the galaxy. Body text #E8E6FF cool white, muted #837DB8 gray-purple. Syntax stays in the purple-blue spectrum: keywords #C084FC bright purple, strings #A6E3FF starlight cyan, functions #60A5FA blue.
How to apply
On macOS, use the Customize command with a nebula/starry background and the galaxy purple-blue: customize-theme-macos.sh --image galaxy.png --name "Galaxy" --accent "#a855f7" --secondary "#4f8ff7" --highlight "#60a5fa". It auto-applies via local CDP.
FAQ for this theme
Is Galaxy good for daytime?
It's dark and moody, better for night or immersive sessions. In bright daylight it may feel dim — nudge the background or text lighter.
How do I restore?

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.
