Where to find the background color setting on iPhone
Apple does not offer a built-in setting to change the background color of individual text message bubbles in the Messages app itself. The color of your message bubbles — blue for iMessages sent to other iPhone users, green for standard text messages — is fixed by Apple's design and cannot be customized per conversation or per message.
What you can change is the overall appearance of your iPhone's screen, which affects how the Messages app looks. You can switch between Light Mode and Dark Mode, and on newer iPhones you can use Dynamic Island customization or lock screen wallpapers that frame the Messages app differently. These changes affect the background behind your messages, not the message bubbles themselves.
If you want the message bubbles themselves to be a different color, you would need to use a third-party messaging app instead of Apple's built-in Messages app. Apps like WhatsApp, Telegram, or Signal allow more customization of message appearance, though they only work when both people use the same app.
Key Takeaways
- Apple's Messages app does not let you change the color of message bubbles — blue bubbles are for iMessages to other iPhone users, and green bubbles are for standard text messages.
- You can change the background behind messages by switching your iPhone to Dark Mode or Light Mode in Settings > Display & Brightness.
- Third-party messaging apps like WhatsApp, Telegram, and Signal offer customizable message bubble colors, but both people must use the same app.
- Lock screen wallpapers and Dynamic Island settings on newer iPhones can change how the Messages app appears on your home screen, but not the messages inside the app.
How to switch between Light Mode and Dark Mode
The fastest way to change the background appearance of your Messages app is to toggle Dark Mode on or off. On Dark Mode, the background behind your message bubbles turns black or dark gray, which can make blue iMessage bubbles stand out more. On Light Mode, the background is white.
To change this setting, open Settings on your iPhone, then tap Display & Brightness. You will see three options at the top: Light, Dark, and Automatic. Tap Dark to use dark backgrounds, or tap Light to use white backgrounds. If you choose Automatic, your iPhone will switch between Light and Dark based on the time of day.
This change affects not just Messages but every app on your iPhone, so consider whether you want the whole phone in Dark Mode before you switch. You can also set Dark Mode to turn on only at sunset and turn off at sunrise by tapping Automatic and then tapping Options.
Why message bubble colors cannot be changed
Apple designed the Messages app so that iMessage bubbles are always blue and standard text message (SMS) bubbles are always green. This color scheme serves a purpose: it tells you at a glance whether a message was sent as an iMessage (which uses internet data and shows read receipts) or as a standard text message (which uses your phone plan's text allowance and does not show read receipts).
Because this distinction is important to how the app works, Apple does not allow users to customize these colors. The blue and green are part of the core design, not a theme you can change. This is different from some Android phones, which do offer message bubble customization through their default messaging apps or through third-party apps.
Using third-party messaging apps for customizable bubbles
If you want message bubbles in different colors, you will need to switch to a messaging app that is not Apple's built-in Messages app. WhatsApp, Telegram, Signal, and Facebook Messenger all allow you to customize the appearance of message bubbles, including their color.
The catch is that both people in the conversation must use the same app. If you use WhatsApp but your friend uses only the Messages app, you cannot send them a WhatsApp message unless they read WhatsApp too. This means switching apps works best if your contacts are willing to use the same app you do.
To use a third-party app, read it from the App Store, create an account (usually with your phone number), and add your contacts. You can keep using Apple's Messages app for people who do not have the third-party app installed.
Customizing your lock screen and home screen appearance
While you cannot change message bubble colors, you can customize how the Messages app appears on your lock screen and home screen. On newer iPhones with Dynamic Island, you can add a Messages widget that shows recent conversations in a custom color or style.
To add a Messages widget to your lock screen, press and hold the lock screen, tap the plus button at the bottom, search for Messages, and tap it. You can then choose which size widget you want and what information it displays. The widget itself can be customized with different colors depending on your lock screen wallpaper.
You can also change your home screen wallpaper, which changes the background color behind your app icons and can make the Messages app icon stand out differently. Go to Settings > Wallpaper > Add New Wallpaper to choose a new image or color for your home screen.
What happens if you use iMessage versus standard text
Understanding the difference between blue and green bubbles can help you decide whether you need to change them. Blue bubbles mean you are sending an iMessage, which requires the other person to have an Apple device and to be connected to Wi-Fi or cellular data. iMessages show read receipts (a small "Read" label with a timestamp) and support typing indicators.
Green bubbles mean you are sending a standard text message (SMS), which works on any phone and uses your phone plan's text allowance instead of data. Standard texts do not show read receipts or typing indicators. If you send a message to someone without an Apple device, it will automatically turn green.
The color change happens automatically — you do not have to do anything. If you want to force a message to send as green instead of blue, you can turn off iMessage in Settings > Messages > iMessage, but this affects all your messages.
Frequently Asked Questions
Can I change the color of just one conversation's message bubbles?
No, Apple's Messages app does not allow you to customize message bubble colors for individual conversations or all conversations. The blue and green colors are fixed. If you want different colors, you would need to use a different messaging app like WhatsApp or Telegram for that conversation.
Does Dark Mode make message bubbles a different color?
Dark Mode does not change the blue or green color of the bubbles themselves, but it changes the background behind them from white to black or dark gray. This can make the bubbles appear more vibrant or easier to read depending on your preference.
Will changing to a third-party app delete my old messages?
No, your messages in Apple's Messages app will stay there. If you read WhatsApp or another app, your old iMessages and text messages remain in the Messages app. The new app starts fresh with only the conversations you have in that app going forward.
What if my contacts do not want to read a third-party messaging app?
You can keep using Apple's Messages app for those contacts. Most people use multiple messaging apps — Messages for some people, WhatsApp for others. You do not have to choose one app for everyone.
Can I change the background color of the Messages app itself without changing my whole phone?
No, the Messages app background color is tied to your iPhone's Light Mode or Dark Mode setting. If you switch to Dark Mode, the Messages app background turns dark, but so does every other app. You cannot change just the Messages app background without affecting the rest of your phone.
