You can now enable dark mode for Google Chat on the web (chat.google.com) and the Google Chat Progressive Web App (PWA). Dark mode creates a better viewing experience in low-light conditions by reducing brightness and potentially reducing eye strain.
Admins: There is no admin setting for this feature.
End users: Within the chat.google.com or the Google Chat PWA, go to Settings > Theme settings and select “Dark mode”.
Available to all Google Workspace customers, as well as G Suite Basic and Business customers
