What Midnight Lizard is

The extension applies dark, light, grayscale, or colorful schemes to any site, with controls for brightness, saturation, contrast, hue, blue-light filtering, and separate colors for text, links, buttons, borders, images, and scrollbars. Schemes apply globally, per site, or by URL pattern, and can run on a schedule.

Feature coverage

  • Editable dark, light, and grayscale color schemes
  • Blue-light filter and image shading
  • Per-site, URL-pattern, and scheduled activation

What stands out

  • High rating on a meaningful sample
  • MIT-licensed open-source code on GitHub
  • Listing declares no data collection

Tradeoffs to know

  • Public development paused from 2021 to 2025
  • Far smaller user base than Dark Reader
  • Deep settings take time to tune

Permissions and privacy

Page access

Recoloring every element on any site requires reading and changing page content everywhere; its manifest requests all-sites access plus storage and scripting. Blacklist or whitelist mode and the per-site toggle (Alt+Shift+L) limit where it acts, and PDF or local-file support only works if you enable file access in Chrome.

Data notes

The listing carries the developer's declaration that it does not collect or use your data, and the extension needs no account. Extra color schemes can be installed from midnight-lizard.org, and the MIT-licensed code is public on GitHub, so the no-collection declaration can be checked against the implementation.

Pricing

Free and open source, with optional donations via OpenCollective. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
