Open Settings and Find the Calendar App

To change calendar colors on iPhone, you need to access the Calendar app itself, not the Settings app. Open Calendar from your home screen — it's the white icon with a date on it. The color-changing options are built into the app, not buried in system settings.

Once Calendar is open, you'll see your list of calendars at the bottom of the screen. Tap the "Calendars" tab if you're not already there. This shows all your calendars — the ones you created, subscribed to, or synced from other accounts like Gmail or Outlook.

Key Takeaways

  • Calendar colors are changed directly in the Calendar app by tapping the info icon next to a calendar name, not through iPhone Settings.
  • Swipe left on any calendar name to reveal the info button, or tap "Edit" in the top-left corner to access color options.
  • iPhone offers 12 preset colors for each calendar, and you can assign different colors to different calendars to organize them visually.
  • Changes to calendar colors sync across all your Apple devices if you use iCloud, but colors for Gmail or Outlook calendars may not change on other devices.

Swipe Left to Reveal the Info Button

The quickest way to change a calendar's color is to swipe left on the calendar name in your Calendars list. A small circle with an "i" (info icon) will appear on the right side of that calendar's row. Tap that circle to open the color menu.

If swiping doesn't feel natural to you, there's an alternative: tap "Edit" in the top-left corner of the Calendars tab. This puts the list into edit mode, and you'll see the same info icons appear next to each calendar name. Tap the info icon for whichever calendar you want to change.

Select a New Color from the Preset Options

Once you tap the info icon, a small menu appears with 12 color circles to choose from. The colors include red, orange, yellow, green, blue, purple, pink, and several shades in between. Tap any color circle to assign it to that calendar when ready — there's no "save" button needed.

The color you choose will appear next to that calendar's name in your list, and all events in that calendar will display in that color on your calendar view. If you change your mind, you can tap the info icon again and pick a different color at any time.

Understand How Colors Work Across Devices

If you use iCloud to sync your calendars, the color changes you make on your iPhone will appear on your Mac, iPad, and any other Apple device signed into the same iCloud account. The color is stored as part of your calendar settings in iCloud.

However, if you've added a Gmail calendar, Outlook calendar, or another third-party calendar to your iPhone, the color you set on your iPhone may not carry over to those services' own apps or websites. The color change only affects how that calendar appears in Apple's Calendar app. The original calendar in Gmail or Outlook will keep its own color scheme in those services.

Organize Multiple Calendars with Different Colors

Using different colors for different calendars makes it much easier to see at a glance which events belong to which calendar. For example, you might use blue for work events, green for personal time, red for family obligations, and purple for fitness activities. This visual separation helps you spot scheduling conflicts and understand your week faster.

You can create as many calendars as you need — work, home, hobbies, shared family calendars, and more — and assign each one its own color. To create a new calendar, tap "Calendars" at the bottom, then tap "Edit" and look for the option to add a new calendar. Once created, you can when ready assign it a color using the same info icon method.

Troubleshoot Color Changes That Don't Appear

If you change a calendar's color but it doesn't show up, first check that you're looking at the right calendar. Tap "Calendars" and make sure the calendar you changed is still checked (has a checkmark). If it's unchecked, the calendar is hidden from view, so you won't see the color change.

If the calendar is checked but the color still hasn't changed, try closing the Calendar app completely and reopening it. Sometimes the display needs to refresh. If you're using iCloud and the color isn't syncing to another device, make sure both devices are signed into the same iCloud account and that Calendar is turned on in iCloud settings on both phones.

Frequently Asked Questions

Can I create my own custom color instead of using the 12 presets?

No, iPhone's Calendar app only offers the 12 preset colors. You cannot create a custom color or pick from a wider color palette. You're limited to the colors Apple provides in that menu.

Will the color I set on my iPhone show up in the Calendar app on my Mac?

Yes, if both devices are signed into the same iCloud account and Calendar is synced. The color will appear on your Mac within a few moments. If it doesn't, check that both devices are connected to the internet and that iCloud Calendar is enabled on both.

What happens to calendar colors if I share a calendar with someone else?

The color you see on your iPhone is personal to your device. When you share a calendar with another person, they can set their own color for that shared calendar on their device. Your color choice doesn't affect what they see.

Can I change the color of individual events instead of whole calendars?

No, you can only change the color of an entire calendar, not single events. All events in a calendar will be the color you assign to that calendar. If you need different colors for different types of events, you'll need to create separate calendars for each type.

Why did my calendar color change back after I set it?

This usually happens if the calendar is synced from another service like Gmail or Outlook, and that service reset the color on its end. Check the original calendar in Gmail or Outlook to see what color it's set to there. You may need to change the color in both places, or accept that the iPhone color will revert periodically.
