About this extension
Knob adds a clean, custom light theme to YouTube Music — something the player still doesn't offer natively. One click and the whole interface turns white: home feed, search, artist and album pages, player bar, queue, menus, comments and settings.

THE KNOB

A tactile dial in the toolbar with three positions:
  • On — force the light theme everywhere on YouTube Music
  • System — follow your Windows light/dark setting automatically
  • Off — back to YouTube Music's own dark theme

Your choice is remembered across sessions, and across devices when your browser sync is on.

DESIGNED, NOT INVERTED

Knob isn't a CSS filter that inverts images and breaks icons. Every surface is individually re-themed for light mode: readable text everywhere, light menus and dialogs, dark buttons on light backgrounds, correctly colored icons, themed comments and settings — including video pages, the mini player and search results.
  • No accounts, no tracking, no data collection
  • Works only on music.youtube.com — no access to any other site
  • Free and open source: https://github.com/isamyadeep/youtube-music-light-mode

If you listen to YouTube Music at night in a bright room, or simply prefer light interfaces, Knob is the missing toggle.

Permissions explained: "Storage" is used only to remember your On/System/Off preference. No data leaves your browser.
Developer comments
Source code: https://github.com/isamyadeep/youtube-music-light-mode
The package is plain JS/CSS — no build step, no minification; the zip contents match the repo's manifest.json, content/, popup/ and icons/ directly.

How to test: install, open https://music.youtube.com (works signed out), click the Knob toolbar icon, and switch On / System / Off. Browse Home, Search, an artist page, and a video song with comments and the settings dialog to see themed surfaces.

Note: the manifest uses "version_name", a Chromium property Firefox ignores — you may see a cosmetic warning; functionality is unaffected.
