Google Messages has spent years being the app Android users defend rather than the app they enjoy. It works, it does RCS, it stopped being ugly around 2021, and that was roughly the extent of the pitch.
That changed on August 27, when Google officially announced Chat themes, a feature that lets you give any conversation its own accent color and its own background image. It is the sort of thing that sounds trivial until you have five group chats that all look identical and you send a photo to the wrong one.
Apple shipped nearly the same feature in iOS 26 a few months earlier. Google’s version is not a straight copy, and the one place it diverges is the place that matters most.
💬 The short version
- Chat themes are official as of August 27, 2026, after a staged rollout that started back in June.
- You get two controls: an accent color for the message bubbles, and a wallpaper behind the conversation.
- Themes are private to you. Nobody on the other end sees the color or the background you picked.
- Apple’s version is the opposite. Change an iMessage background and it changes for everyone in the thread.
- RCS is required. A thread still running on SMS or MMS will not show the option at all.
- Wallpapers come from a curated gallery across categories including Landscapes, Space, Architecture, Cityscapes, Macro, and Textures, or you can upload your own photo.
- The rollout is server side. Two people on identical app versions can still see different things, and the feature has appeared and disappeared for some users.
How to Set One Up
The whole flow lives inside a single conversation, which is why plenty of people have the feature and have not noticed it.
Five steps, about twenty seconds
1. Open Google Messages and go into the conversation you want to change.
2. Tap the contact name or group name at the top of the screen.
3. Tap the More menu in the upper right, then choose Chat theme.
4. Pick an accent color from the palette. Under Wallpapers, either browse the preset categories or tap Choose a photo to pull one from your gallery.
5. Check the live preview, then tap Apply.
If Chat theme is not in that menu, skip to the troubleshooting section further down. There are two common reasons, and only one of them is fixable.
What You Can Actually Change
The feature replaces the old Change colors option that Google added in 2024, which only ever swapped the bubble color and did nothing about the background. The new version does both, and the two settings are linked in a way that is genuinely thoughtful.
When you set a wallpaper, the message bubbles automatically retint to complement it, so you do not end up with a pale blue bubble sitting on a bright orange sunset. If you dislike the automatic choice, you can override the palette manually afterward.
Roughly what a themed thread looks like
Bubbles take the accent color you choose. The wallpaper sits behind them.
Only you see this. On the other person’s phone the same conversation keeps whatever theme they set, or none at all.
The preset wallpaper gallery is broader than most first party collections. Google groups it into categories including Animals, Architecture, Black and White, Cityscapes, Landscapes, Macro, Space, Sunsets, and Textures. The Textures set is the one worth trying first, because a busy photograph behind a wall of text gets tiring in about a day, while a subtle texture does not.
The One Difference From Apple That Matters
Here is the split, and it is not a small implementation detail. It is a philosophical decision about whose phone the setting belongs to.
| Behavior | Google Messages | Apple Messages (iOS 26) |
|---|---|---|
| Who sees your theme | Only you | Everyone in the thread |
| Can someone else override it | No | Yes, anyone in the chat can change it |
| Syncs to your other devices | Tied to the device | Syncs across iPhone, iPad, and Mac |
| Background sources | Curated gallery or your own photo | Photos, gradients, dynamic themes, AI generated |
| Requirement | RCS enabled | iOS 26 on both ends to see it |
Apple’s approach has a certain logic. A shared background is a shared space, like a group chat photo, and there is something nice about a family thread everyone agrees looks like a beach. In practice it produces a small, constant social friction: your sibling redecorates the group chat, you did not ask for it, and turning it off means either a conversation or digging through settings. We wrote about that in detail when the feature landed, including how to stop other people’s iMessage backgrounds from appearing on your phone, and the volume of people looking for that answer told its own story.
Google looked at the same feature and decided the theme is a property of your app, not of the conversation. That has a real cost, since you cannot coordinate a look with a group, and it does not follow you to a tablet. But it removes an entire category of annoyance, and it means the setting cannot be used to inflict anything on anyone.
For a personalization feature, private is almost always the right default. Wallpaper is a personal choice. Nobody should be able to change yours.
Why the Option May Be Missing
Two things gate Chat themes, and they explain nearly every case of someone tapping through the menu and finding nothing.
The two reasons Chat theme is not there
1. The thread is not on RCS. Chat themes only exist inside RCS conversations. A contact who is on plain SMS or MMS, or a thread that fell back to SMS, will not offer the option even though RCS is switched on elsewhere in your app. Check for the RCS indicator in the message field before assuming the feature is broken.
2. Google has not enabled it for your account yet. This is a staged server side rollout, not a version number. Updating the app from the Play Store does not force it, and the feature has arrived, vanished, and come back for some users during the rollout. There is no reliable trick to speed it up.
The RCS requirement is worth understanding rather than resenting. Themes are part of the richer chat layer, not the twenty year old SMS spec, and that layer is where nearly every recent Messages improvement has landed. It is also where the security improvements live: RCS between Android and iPhone finally added end to end encryption across platforms this year, which was the last real argument for keeping a separate messaging app installed.
If a specific contact keeps dropping to SMS, the usual causes are a carrier that has not provisioned RCS, a phone with RCS disabled in Messages settings, or a contact using a different default SMS app. That is a fixable problem on their end, not yours.
What Else Landed Alongside It
Chat themes got the headline, but the same rollout window brought a cluster of smaller changes, several of which are more useful day to day.
| Feature | What it does |
|---|---|
| Notification snooze | Long press a chat and mute it for 1 hour, 8 hours, 24 hours, or indefinitely. Snoozed threads gray out with an icon. |
| Delete for everyone | Removes a sent message from the recipient’s thread, in RCS chats only. |
| Group chat icons | Custom icons for group threads, which pairs naturally with per chat themes. |
| Editable Smart Replies | A tapped suggestion now drops into the text field instead of sending instantly, so a mis-tap is no longer a sent message. |
| Partial text copy | Long press a message to open a floating menu over a blurred background, then select just part of the text. |
The editable Smart Replies change is the quiet winner. Accidentally firing off a canned “Sounds good” to your boss has been a recurring Android embarrassment for years, and putting the suggestion in the compose field instead of the outbox fixes it properly.
Is It Worth Bothering With
Personalization features are easy to dismiss, and this one has an obvious answer to the “why” question that has nothing to do with decoration.
If you keep several similar looking group chats, a distinct color per thread is a fast visual check that you are typing into the right one. Work threads in one color, family in another, and the wrong window becomes obvious before you hit send rather than after. That alone justifies the twenty seconds of setup, and it is the same reason Apple gave for shipping backgrounds in the first place.
The limitations are real. It does not follow you to another device, it does nothing for SMS threads, and the wallpaper gallery, while broad, is not as flexible as Apple’s gradients and generated options. None of that undermines the core of it.
The Bottom Line
Google Messages took a feature Apple shipped first and made one meaningful change to it: the theme belongs to you, not to the conversation. That decision costs a little coordination and removes a lot of friction, and it is the more defensible call.
If you have RCS on and the option in your menu, set a color on your two busiest group chats today. If the option is missing, confirm the thread is actually running on RCS before you go looking for a fix, because in most cases that is the whole explanation. Everything else is Google flipping a switch on its own schedule, and there is nothing to do but wait.
