Google Messages officially announces ‘Chat themes’ & backgrounds

Google has officially announced new custom chat themes and background wallpapers for the Google Messages app on Android. The feature allows users to personalize individual conversations with unique colors and images, though it remains private to the user's device.
Why it matters
This update enhances user experience and personalization within one of the world's most widely used messaging platforms, signaling Google's continued investment in RCS-based communication.
After beta testing in recent weeks, Google Messages today officially announced custom chat themes and backgrounds on Android.
Requiring RCS, the goal is to “make every conversation feel uniquely yours by customizing the colors and background wallpapers for individual chats.”
Whether you want a favorite family photo behind your main group text or a sleek, minimal color palette for your work contact, the choice is entirely up to you!
Chat themes let you change the bubble accent color and the chat wallpaper. Google offers a gallery of “curated” backgrounds with categories like Animals, Landscapes, and Space. You can also upload your own image.
After making a selection, the “message bubbles automatically adjust to perfectly complement the new scheme.” That said, you can “manually tweak the color palette anytime” with the top carousel.
