Call native settings native
Use Codex's built-in appearance controls where available and do not rename them as a custom installed theme.

Codex appearance settings
Know what belongs in Codex Appearance settings.
Theme language can hide an important distinction. Native choices that Codex exposes in Appearance are different from a downloadable pack's visual tokens, and both are different from an advanced background supplied by an unofficial local compatibility layer.
Design perspective
Make the visual idea survive the work.
A custom pack should never imply that it registers a new named theme inside Settings > Appearance unless the product actually supports that behavior. Describe exactly which values are native, which belong to the pack, and which require the local runtime.
This boundary improves support. Users know where to change a native mode, where to replace an asset, and how to stop the optional layer without searching for a setting that does not exist.

Practical answers
Questions worth answering before you choose.
Will a downloaded theme appear in Settings > Appearance?
No. Native appearance options may appear there, but a downloaded pack does not become a new named option. Advanced artwork is handled by the optional unofficial local compatibility layer.
What parts of a theme are portable?
A manifest, visual tokens, responsive artwork, preview images, checksums, asset source notes, and platform instructions can be packaged and moved between supported setups.
Can I use only the native appearance options?
Yes. You can ignore or restore the optional artwork layer and continue with Codex's native appearance choices. The delivery should make that boundary and path explicit.

Platforms and setup
Create a Codex background image that fits the interface.
The best Codex background is designed around what will cover it. It offers a calm field under navigation and task surfaces, places the meaningful subject toward a safe outer region, and includes enough visual context to survive three desktop ratios.
Read the guide →Platforms and setupChoose a Codex theme with restoration built in.
Customization is easier to trust when the return path is designed at the same time as activation. A reversible pack keeps its files separate from the signed application, exposes what is active, and offers a clear command to stop the optional layer and return to native Codex.

A good light theme feels open without becoming a white field with floating controls. Slightly tinted canvases, clear border values, dark neutral text, and restrained highlights make the workspace comfortable in real daylight.
Read the guide →Use casesA Codex theme for designers who notice the details.
Designers can push a theme beyond generic dark mode, but the best result still behaves like a product surface. It needs a coherent material idea, intentional spacing, accessible interaction states, and artwork that survives real window geometry.
