A chat theme changes the colours and background of a single Instagram conversation. It is a small feature with an outsized following, partly because it is genuinely useful for telling threads apart and partly because it is one of the few things Instagram lets you personalise at all.
This guide covers where the setting lives, the detail people miss about who sees the change, what to do when the option is not there, and whether you can build your own.
Key Takeaways
How to Change an Instagram Chat Theme
Four taps, and all of them happen inside the conversation itself.
Open the Conversation
Themes are set per chat, so you have to be inside the thread you want to change.
Tap the Name or Photo at the Top
This opens the chat details screen, which holds the theme, nicknames and privacy controls for that conversation.
Tap Theme
On most versions it sits near the top of the list, sometimes labelled Chat theme.
Pick a Theme
Gradients, solid colours and seasonal sets. Selecting one applies it instantly.
Confirm It Applied for Both
Send a message and check. The theme is shared, so the other person sees it too – which surprises a lot of people.
The Detail Most People Miss
A chat theme is a property of the conversation, not of your app. When you change it, the other person’s view of that thread changes as well, immediately and without being asked.
There is no private or one-sided theme. If you want a thread to look different only to you, that is not something Instagram supports.
- Both participants see the same theme.
- In a group chat, everyone sees it and any member can usually change it.
- There is no notification, but the change is visible next time they open the chat.
- Either side can change it back at any time.
Why the Theme Option Is Missing
This is the second most common question after how to change it, and the causes are mundane.
| Symptom | Likely cause | Fix |
|---|---|---|
| No Theme entry at all | App version is behind | Update Instagram and reopen the chat |
| Option appears in some chats only | Staged rollout | Wait; it arrives at different times per account |
| Greyed out in a group | Group restricts changes | Ask an admin, or check group settings |
| Themes look different from a friend’s | Different app version or region | Normal; the set varies |
| Theme reverts on its own | Sync issue or the other person changed it | Reapply and check with them |
Can You Make a Custom Chat Theme?
No. Instagram gives you a fixed set of themes and does not allow custom colours, uploaded backgrounds or imported palettes. Any app or site offering custom Instagram chat themes is either selling wallpapers for something else or attempting to harvest your login.
The set does change over time – seasonal and partnership themes appear and are retired – so a theme a friend has may simply be one you have not received yet, or one that has been withdrawn.
- No custom colours or uploaded images.
- No third-party theme packs, whatever they claim.
- The available set varies by app version and region.
- Never install an app that asks for your Instagram password to change a theme.
Using Themes to Organise a Busy Inbox
The practical use of themes is visual sorting. If you run a business account and your inbox mixes suppliers, customers and personal chats, a consistent colour per category makes the right thread findable at a glance.
- One colour per relationship type – customers, suppliers, team.
- A distinct theme for anything urgent, so it stands out while scrolling.
- Leave low-priority chats on the default so the coloured ones mean something.
- Remember the other side sees it, so pick something neutral for customer threads.
- Themes do not survive as a system – for real organisation you need a DM CRM rather than colours.
Themes vs Other Ways to Organise Instagram DMs
| Method | Visible to them | Scales past ~20 chats | Best for |
|---|---|---|---|
| Chat themes | Yes | No | Spotting a specific thread quickly |
| Pinning chats | No | Barely | Three or four active conversations |
| Primary / General tabs | No | Somewhat | Separating known from unknown |
| Flagging (professional accounts) | No | Yes | Marking threads to return to |
| A DM CRM | No | Yes | Actual pipelines and team handover |
Once the inbox is genuinely busy, colours stop helping. That is the point at which message requests start piling up unread and something more structured is needed.
Themes, Nicknames and the Rest of the Chat Screen
The theme sits alongside several other per-conversation controls people rarely open.
- Nicknames change how names display for both of you in that thread.
- Mute silences the thread without the other person knowing.
- Restrict and block are here too; see the full guide to turning off DMs.
- Disappearing messages and vanish mode are per conversation.
- Media and links gives you a searchable history of what was shared, useful when recovering an old message.
- Sending limits still apply in every thread; see Instagram’s DM limits.
- Video and media have their own quirks – sending videos in DMs covers those.

Conclusion
Changing an Instagram chat theme takes four taps inside the conversation, and the important detail is that the change applies to everyone in that thread rather than just to you.
Custom themes do not exist, and any app promising them is a risk rather than a feature. A missing Theme option is almost always an outdated app or a staged rollout.
As a way of telling a few threads apart, themes work well. As an organisational system for a business inbox, they stop scaling quickly.
If your inbox is where sales happen, turning DMs into sales is a better use of the same half hour.
