What High Contrast is

After install, pages are inverted by default; the toolbar button switches between filters that raise contrast, flip black and white, or remove color, and remembers a choice per site. The developer says it filters nearly everything except photos, and Chrome's own pages such as the Web Store and New Tab stay unaffected.

Feature coverage

  • Contrast, inverted, and grayscale color filters
  • Per-site color scheme settings
  • Keyboard shortcut for quick filter changes

What stands out

  • Published by Google's Chrome accessibility team
  • Listing declares no data collection
  • Free, with source code in the Chromium project

Tradeoffs to know

  • 3.5 rating on a large sample
  • Inverts every page by default after install
  • Fewer color controls than Dark Reader or Midnight Lizard

Permissions and privacy

Page access

A page-wide filter has to run everywhere: the Chromium source shows access to all URLs and frames from the moment a page starts loading. Chrome's own pages, such as the Web Store, New Tab, and Settings, are off-limits by design. Per-site settings or Chrome's site-access controls narrow where it acts.

Data notes

The listing carries the developer's declaration that it does not collect or use your data, and the extension needs no account. Filters are applied inside the page rather than through a remote service, and the code is published in the Chromium repository, so the declaration can be checked against the implementation.

Pricing

Free; source code is part of the Chromium project. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
