Google is exploring the integration of wallpaper-based theming within its Gemini feature in the Google app, aiming to unify the visual experience across applications and phase out the white-and-blue color scheme. The experimentation is underway with version 17.12.51 of the Google app, where users have noticed changes in the Gemini overlay that adapts to the user's wallpaper. The overlay now features a subtly tinted bar and a darker button for Gemini Live, reflecting the system's theme. However, other elements like button shapes remain unchanged. The main Gemini app still displays its traditional colors, indicating that the rollout of the theming feature is in its early stages. Insights from an APK teardown suggest potential future features, but some may not reach public release.
