Change your chat background & colors
You can use themes to customize your chat's background and colors in Allo for individual and group chats. Themes aren't available in a Google Assistant chat.
If you've recently downloaded or upgraded Allo, it could take a few hours for the app to enable the theme setting.
Change the theme
- On your computer, open Allo for web.
- Open the chat where you want to change the theme.
- In the top right, click the profile icon.
- In "Change chat theme," scroll through the themes until you find the one you want.
- Click the chat to continue messaging.
