# Browser Accent Color Experiments

This directory contains experiments for applying the dynamic accent color
provided by `core/accent.h` to web browsers.

## Ungoogled-Chromium

Ungoogled Chromium exposes limited theming hooks and does not support
changing its UI colors at runtime. Applying a dynamic accent color would
require maintaining a custom patch set or an extension that continually
re-themes the browser, which is outside the scope of this repository.

## Firefox

Firefox can be themed programmatically. The files here demonstrate two
approaches:

1. `firefox/update-userchrome.sh` writes a minimal `userChrome.css` using the
   current accent color. Run it whenever the accent color changes.
2. `firefox/extension/` contains a small WebExtension and native messaging host
   that continuously updates a `--accent-color` CSS variable across all pages.

To use the extension:

1. Build the helper program:

   ```sh
   ./build.sh
   ```

2. Register the native messaging host:

   ```sh
   firefox/install-native-host.sh
   ```

3. Load `firefox/extension` as a temporary extension from `about:debugging`.

These scripts are meant as a starting point for proper browser ricing and can
be adapted to other workflows.
