How to customize Codex Desktop beyond colors and fonts
A practical map of native Codex appearance controls, advanced desktop skins, safe previews and the limits of UI customization.

Use the native layer first
Native appearance settings are the most stable option because they move with the app. They should own basic color, accent and font choices whenever possible.
- Choose light, dark or system appearance
- Set supported UI and code fonts
- Share an official theme format when it covers the intended result
Add only the advanced layer you need
Whole-window artwork, optional MP4 backgrounds and controlled translucent surfaces sit beyond a basic palette. Preview them against representative task, terminal, diff and settings fixtures before exporting.
- Keep controls and text distinguishable over media
- Prefer a static image or reduced effects for long sessions
- Keep native colors, typography, radii and component layout owned by the client
Check the trust boundary
A theme should describe appearance, not execute arbitrary code. Confirm the target app version, inspect the package contents and know how to return to the native appearance before applying anything outside the official format.
Frequently asked questions
Can CC Theme change Codex product features?
No. It works at the appearance layer. Visual width, spacing or surface changes do not create folders, restore removed data or add application features.
Do I need an advanced skin for a new color scheme?
Usually not. Use the official Codex theme format when built-in colors and fonts are enough.
