The short version: you change the chat colour in an Instagram DM by opening the conversation, tapping the person's name at the top, then tapping "Theme" to pick a preset colour. It only changes the colour for you and the other person in that one thread, it does not change your app theme, your profile, or anyone else's view of your other chats.
Where the setting lives
This is the bit that trips people up because Instagram has buried it two menus deep and renamed it a few times over the years. Here is the current path, step by step, as of the 2026 app version:
- Open Instagram and go to your DMs
- Tap into the specific conversation you want to change
- Tap the person's name or profile picture at the top of the screen
- Scroll down to "Theme"
- Tap it, scroll through the colour swatches, select one
That's it. No save button, it applies the second you tap the swatch. If you want to go back to the default Instagram gradient, scroll to the top of the theme options and there's usually a default or "none" option sitting first in the row.
A worked example to make this concrete
Say you run a small online shop selling handmade candles and you message suppliers, customers, and your sister all through Instagram DMs on the same account. You could set your supplier thread to a plain grey so it reads as business, keep your sister's thread on the pink default theme Instagram gives you, and set a customer complaint thread to a neutral blue so it doesn't blend in visually with your more casual chats when you're scrolling fast looking for it. None of this is complicated, it's just visual filing. The colour change takes about 15 seconds per thread once you know where the menu is.
What changing the colour does and doesn't do
People assume this is a bigger feature than it is, so let's be blunt about the limits:
- It only changes bubble colour in that one conversation, for both people in it
- Group chats have the same Theme option, usually accessed by tapping the group name or the info icon
- It does not change notification sounds, fonts, or chat wallpaper, because Instagram DMs don't have a wallpaper feature the way WhatsApp does
- It does not let you set a custom hex code, you're picking from Instagram's own preset list, which currently sits around a dozen colours plus a couple of gradient options
- Changing it doesn't notify the other person with an alert, though some versions of the app do show a small "chat theme changed" message in the thread
That last point matters more than people admit. If you're trying to use a colour change as a quiet signal, like changing a chat to red to mark it as urgent for yourself, remember the other person can see that change too and might ask why. It's not a private setting, it's a shared one, because you're both looking at the same thread.
The uncomfortable bit nobody mentions
Most guides on this topic present chat colour as a fun personalisation trick, and fine, it is. But if you're hunting for this setting hoping it'll fix the actual problem, which for a lot of people is "I can't find important messages in my DMs," colour alone won't solve that. Instagram doesn't let you pin threads by colour, search by colour, or filter your inbox by colour. You're relying entirely on your own memory of which thread is which shade, and once you've got more than six or seven coloured threads, that system falls apart. I'd treat chat colour as decoration, not organisation. If you need to manage high DM volume for a business account, you're better off using Instagram's built-in filters (Primary, General, Requests) alongside labels in a tool like Meta Business Suite rather than relying on colour memory.
Common problems people hit
A few things that generate a lot of confused searches:
- "I can't find the Theme option" usually means you're on an older app version, or you're looking in the chat settings cog rather than tapping the name directly. Update the app first.
- "It changed back on its own" can happen after you uninstall and reinstall Instagram, since some custom settings don't always carry over cleanly.
- "My colour choice looks different on their phone" is not possible under normal settings, the theme is shared, but display differences between an iPhone and an Android screen can make the exact same colour look slightly warmer or cooler.
If you spend a lot of time inside Instagram tweaking small visual details like this, it's worth knowing the platform's other visual tools too. People searching chat colour settings are often the same people who later want to know what Snapchat's story icons mean, or who end up asking an AI tool to edit a photo for a profile picture and want to know how to edit a photo without changing their face in the process.

If you're using DMs for business
For anyone running customer service or sales through Instagram DMs, colour coding threads by hand doesn't scale past a handful of conversations a day. If you're getting dozens of DMs daily and trying to track which ones need replies, which are sales leads, and which are spam, that's a workflow problem, not a colour problem, and it's the kind of thing worth getting real advice on if your business depends on it. A short conversation with an AI consultant for small business can save you weeks of fiddling with workarounds that were never built for volume.
On the creative side, if you're already in Instagram tweaking visuals, it's worth knowing what else is possible with free AI tools. A lot of people who care about chat appearance also enjoy colourising old family photos with Gemini or experimenting with writing effective ChatGPT picture prompts for their profile grid.

Frequently asked questions
Can I change the Instagram DM colour without the other person seeing?
No. Chat theme is shared between both people in the thread, so if you change it, they see the new colour too, and some app versions show a small system message noting the change.
Why don't I have the Theme option in my Instagram DMs?
This is almost always an outdated app version. Update Instagram from the App Store or Google Play, then check the person's name at the top of the chat again for the Theme menu.
Can I set a custom colour instead of Instagram's presets?
No, as of 2026 Instagram only offers a fixed list of preset colours and gradients, there's no custom hex code or colour picker option.
Does changing the chat colour affect notifications or sounds?
No, colour is purely visual inside the thread. Notification sounds, vibration, and mute settings are separate and controlled from the same chat info menu but under different options.
