Learn ForcedSkin
Short articles on what ForcedSkin is, how to apply a custom website theme, and how to control theming per site.
Getting started
What is ForcedSkin?
ForcedSkin is a Chromium extension and marketplace that applies one CSS colour theme across ordinary websites without inverting the screen.
How ForcedSkin works
ForcedSkin injects a local CSS recolour engine that maps interface colours to your palette whilst leaving media pixels and page structure alone.
Themes and colours
Custom website themes
A custom website theme in ForcedSkin is a coordinated CSS palette you apply across sites from the marketplace — not a redesigned page.
Change a website theme in your browser
You change a site’s colours in ForcedSkin from the extension popup and marketplace palettes — not by editing the website or inverting the screen.
Browser theme extension for webpages — not Chrome UI
ForcedSkin is a Chromium extension that themes website CSS; it is not a Chrome Web Store “browser theme” for the toolbar or settings chrome.
Website dark mode without invert filters
ForcedSkin provides website dark mode by remapping CSS interface colours to a dark palette, not by inverting every pixel on the screen.
Site control
Site adapters (forcedskin-adapter-formula/v1)
Site adapters are declarative JSON formulae that fine-tune ForcedSkin’s CSS recolouring on specific websites without replacing the universal engine.
Exclude websites from ForcedSkin
ForcedSkin’s per-site whitelist excludes chosen hostnames from CSS theming so they keep native colours whilst the rest of the web uses your palette.
