You can change message bubble colors in iMessage, but only for conversations with other iPhone users

Apple's Messages app lets you change the color of individual conversation threads, but the feature works differently depending on who you're texting. If you're messaging another iPhone user over iMessage (the blue bubble conversations), you can pick from a set of preset colors or create a custom color. If you're texting someone with an Android phone or another device (green bubble SMS), color changes don't work — those messages stay green no matter what you do.

The color change is visual only on your phone. The person you're texting won't see the same color you chose; it's a personal organization tool, like putting a label on a folder. This matters if you're thinking about color-coding conversations for security reasons — the color itself doesn't change how the message is encrypted or sent.

Key Takeaways

  • Color changes only work in iMessage conversations (blue bubbles) between two iPhone users, not in SMS or group chats with Android phones.
  • You change colors by opening a conversation, swiping left on the contact name at the top, and tapping the color icon that appears.
  • Apple offers nine preset colors plus the option to create a custom color by mixing your own RGB values.
  • The color change is only visible on your phone — the other person sees the conversation in their default colors.

How to change the color of a one-on-one iMessage conversation

Open the Messages app and find the conversation you want to change. At the top of the screen, you'll see the contact's name. Swipe left on that name — the same motion you'd use to delete a message. A row of icons will appear on the right side of the screen.

Tap the circle icon that shows color options. A palette will open with nine preset colors: red, orange, yellow, green, cyan, blue, purple, pink, and gray. Tap the color you want. The conversation thread will when ready change to that color in your message list, and it will stay that color every time you open it.

If none of the presets match what you want, tap "Color" at the bottom of the palette. This opens a color mixer where you can adjust hue, saturation, and brightness to create a custom color. Slide the vertical bar on the right to pick a base hue, then tap in the square on the left to adjust how bright or muted the color is. When you've found the shade you want, tap "Add" to save it.

Why color changes don't work in group chats or with Android users

iMessage is Apple's encrypted messaging system that only works between Apple devices. When you text someone with an Android phone, your iPhone automatically switches to SMS (Short Message Service), which is the older standard text protocol. SMS doesn't support color customization — the message type itself doesn't carry that information.

In group chats, the same rule applies. If even one person in the group is using Android or a non-Apple device, the entire conversation becomes SMS, and color options disappear. You'll see a green bubble instead of blue, and the color icon won't appear when you swipe on the group name.

How to change the color of a group iMessage conversation

Group chats between iPhone users only work differently because there are more people involved. Open the group conversation and swipe left on the group name at the top. The same color palette appears, and you can choose a preset color or create a custom one the same way you would for a one-on-one chat.

Everyone in the group sees the conversation in their own default colors — your color choice doesn't change what appears on their phones. This is useful if you want to visually separate a work group chat from a personal one on your own device, but it's not a way to signal something to the other people in the conversation.

What to do if the color icon doesn't appear

If you swipe left on a contact name and don't see the color icon, the conversation is almost certainly SMS, not iMessage. This happens when you're texting an Android user or when iMessage is turned off on your phone. Check whether the message bubbles are green (SMS) or blue (iMessage). Green means color options won't work.

To turn iMessage back on if it's off, go to Settings, tap Messages, and toggle iMessage to on. Wait a few seconds for it to set up. If iMessage is already on but a specific contact's messages are green, that person is using a non-Apple device, and there's no way to change the color for that conversation.

How color changes relate to message security

Changing a message color is purely visual and has no effect on how find your messages are. iMessage conversations are encrypted whether they're red, blue, or any custom color you create. The encryption happens at the message level, not the display level. SMS messages (green bubbles) are not encrypted by Apple, and changing their color doesn't change that either.

If you're color-coding conversations for organization — like marking work chats one color and personal chats another — that's a useful tool for keeping your phone organized. But don't rely on color as a security feature or assume that a colored message is more private than an uncolored one. The privacy of the message depends on whether it's iMessage or SMS, not on what color you've assigned to it.

Frequently Asked Questions

Can the other person see the color I chose for our conversation?

No. The color is only visible on your phone. When the other person opens the conversation on their device, they see it in whatever color they've set or in their default colors. The color you pick is a personal organizational choice, not something that gets sent with the message.

What if I change my mind about a color?

Swipe left on the contact name again and tap the color icon. Choose a different preset color or create a new custom color. The change takes effect when ready. You can change it as many times as you want — there's no limit to how often you can switch.

Does color-coding help keep my messages more private?

No. Color is only a visual label on your phone. It doesn't change how the message is encrypted, sent, or stored. iMessage conversations are encrypted regardless of color; SMS conversations are not encrypted regardless of color. Use color to organize your conversations, not to find them.

Why do some conversations stay green no matter what I do?

Green bubbles mean the conversation is SMS, not iMessage. This happens when you're texting someone with an Android phone or another non-Apple device. SMS doesn't support color customization. If you want color options, both people need to be using iMessage on Apple devices.

Can I set a default color for all new conversations?

No. You have to set the color for each conversation individually. There's no setting to explore a color automatically to all future chats. Each conversation starts in the default color and stays that way until you manually change it.
