TL;DR
- Google Messages is quietly rolling out the ability to set custom chat themes for standard SMS conversations.
- Chat themes were previously limited to RCS chats in the messaging app.
- This change may have been facilitated by chat themes being limited to the person who set it rather than everybody in the conversation.
While Google Messages has long let users customize their RCS chats with a selection of colors, it got a major upgrade in August with the introduction of chat themes, a feature we first uncovered in May. One key limitation of this customization tool is that it only works with RCS chats. It now looks like Google has flipped the switch for standard SMS/texts, too.
As a Reddit user points out, Google Messages appears to have quietly enabled chat themes for non-RCS chats. A quick look on my Pixel 6a confirms this, with a red dot prompting users to try it for the first time.
