High contrast mode

By default, some visual elements in Zulip (such as date/time stamps, certain buttons, links and unread counts) are intentionally light. High contrast mode increases the contrast of these elements to meet the AA level of the W3C's Web Content Accessibility Guidelines.

  1. Click on the gear () icon in the upper right corner of the web or desktop app.

  2. Select Personal settings.

  3. On the left, click Preferences.

  4. Under Preferences, select High contrast mode.
