Google is developing a Custom theme section for Google Messages, introducing deeper chat personalization to the app. The update, spotted in app strings, was designed to let users tweak backgrounds and bubble colors, featuring photo uploads and Google Photos integration for personal wallpapers. It aimed to offer a Theme Preview so changes could be reviewed before applying.

Additional taps point to independent bubble-color controls and the ability to mix and match elements rather than rely on fixed theme packs. The interface appeared to centralize options into a single Custom area and streamline importing images from Google Photos, reducing friction for users migrating from Samsung Messages.

For consumers, the change matters because it restores visual personality to conversations, improving user satisfaction and retention. By matching features people valued in Samsung Messages, Google Messages could close a customization gap and make RCS-era chat windows feel more personal.
