The following page shows accessibility issues in various projects in the standard (light) theme and the new night theme (aka dark mode). We run color contrast checkers against the desktop site in both the light and night themes and communities can use this tool to identify high priority issues for them to fix. The WCAG color contrast checker Chrome extension can help identify colors that should be changed to meet guidelines. Reports are run weekly but you can run reports quicker and more frequently by downloading and running the color contrast tool locally.

A recommendations page should provide all the guidance needed to address issues for the night theme.

When a community has fewer errors in the night mode theme than the light mode theme, the web team will consider broadening the release to desktop and all logged in users. Thank you in advance for your help!

If you would like a report generated for your wiki please ping [[user:Jon (WMF)]] on your local wiki to be added here!

Tier 1 and 2

For these wikis, dark mode is currently available for all users on mobile and desktop.

Tier 3

These wikis only get dark mode for logged in users.

Availability for logged out users will be expanded when more errors have been fixed. The criteria for promoting this feature for anonymous users is when there is less than a 20% increase in errors for the top 500 articles. This list only shows the top 50 articles so these numbers may be different. Wikis can request reassessment for anonymous users once they turn green or orange at any point after July 16th and we will provide a more detailed analysis of the top 500 to aid your work.

Request dark mode for your project.

Tier 4

The following wikis still have legacy Vector as the default skin so dark mode is not available to anonymous users.

Please talk to your local community about changing the default skin to provide dark mode to your users.
