TL;DR
  • Google Messages is rolling out custom chat themes and wallpapers after months of testing.
  • You can use preset backgrounds or your own photos, with matching message bubble colors.
  • Themes are private to you, and RCS must be enabled to use them.

We first spotted Google working on custom chat themes for Messages back in May — a feature that users of some other messaging apps have had for a while. Google is finally catching up on that front today, announcing that users can personalize individual conversations with custom colors and wallpapers.

In a Messages Community post, Google explained that users can now change both message bubble colors and chat backgrounds. You can choose one of Google’s preset wallpapers, pick an image from your own gallery, or stick with a simpler color theme.
