Extension Metadata

About this extension
Omarchy Web Theme recolors the web to match your current Omarchy theme, so pages blend into the rest of your desktop instead of fighting it.
  • Any site, one engine. Backgrounds, borders and shadows are drawn from the theme's surfaces; text, icons and links from its inks. Saturated colors (links, buttons, status) keep their hue by matching the theme's chromatic slots.
  • Readable by construction. Every mapped pair is checked and repaired to at least 4.5:1 (WCAG AA), preferring the theme's own colors over literal black/white.
  • Follows light/dark. Switching Omarchy themes repaints open tabs immediately: a small native-messaging host is signalled by Omarchy's own theme-set hook.
  • Role-aware. A page's background stays a background and its text stays text, even when the site's own light/dark mode disagrees with the theme.
  • Omarchy 4+ on Arch Linux. The extension reads the active theme from ~/.local/state/omarchy/current/ through a companion native-messaging host.
  • The native host, installed by this project's installer or the omarchy-web-theme AUR package (omarchy-web-theme-setup).

Without Omarchy and the native host the extension installs and injects cleanly, but has no theme to read and does nothing.


yay -S omarchy-web-theme # native host + extension
omarchy-web-theme-setup # per-user hook + browser wiring


Then fully quit and restart Firefox. Full source and setup instructions: <https://github.com/skooda/omarchy-web-theme>


The extension collects nothing and sends nothing. It reads your local theme through the native host and makes no network requests of its own.
