Open Settings and find the calendar you want to change

To change a calendar's color on iPhone, open the Calendar app and tap Calendars at the bottom of the screen. You will see a list of all your calendars — the ones you created yourself, plus any shared calendars or subscribed calendars. Find the calendar whose color you want to change.

Next to each calendar name, you will see a colored dot. That dot shows the calendar's current color. Tap the three dots or the info icon next to the calendar name. The exact button depends on your iOS version, but it will be to the right of the calendar name.

Select a new color from the color picker

After you tap the info button, a menu will open. Look for an option that says Color or shows a palette icon. Tap it to open the color picker.

iPhone offers a set of preset colors: red, orange, yellow, green, blue, purple, gray, and sometimes additional shades depending on your iOS version. Tap the color you want. The change takes effect when ready — you do not need to confirm or save.

Key Takeaways

  • Open the Calendar app, tap Calendars at the bottom, and find the calendar you want to change.
  • Tap the three dots or info icon next to the calendar name to open its settings.
  • Select Color from the menu and choose from the preset color options available on your device.
  • The color change applies right away across all your devices that use the same Apple ID.
  • Subscribed calendars and system calendars like Holidays cannot be recolored because they are read-only.

Why you might want to change calendar colors

Assigning different colors to different calendars makes it easier to see at a glance which events belong to which calendar. If you have a Work calendar, a Personal calendar, and a Family calendar, color-coding them helps you spot conflicts and understand your schedule faster.

Colors also sync across your iPhone, iPad, and Mac if you use the same Apple ID. When you change a calendar's color on your iPhone, that change appears on your other devices within a few seconds. This means you do not have to change the color separately on each device.

What to do if the color option does not appear

If you do not see a Color option, the calendar may be read-only or subscribed from another source. Subscribed calendars — like holiday calendars or shared calendars from other people — often cannot be recolored on iPhone. You can only change the color of calendars you created yourself or calendars you have full editing rights to.

If the calendar is one you created and still no color option shows, try closing the Calendar app completely and opening it again. Sometimes the menu does not load on the first try. You can also check whether your iOS is up to date by going to Settings, then General, then Software Update.

How to organize calendars by color

Once you have assigned colors, you can use them to organize your view. In the Calendars list, you can turn calendars on and off by tapping the checkmark next to each one. This lets you focus on just the calendars you want to see — for example, hiding your Work calendar on weekends or hiding your Personal calendar during business hours.

You can also create new calendars and assign them colors from the start. Tap the plus icon in the Calendars section, name the calendar, and choose a color before you save it. This way you can build a color system that matches how you actually use your time.

Changing colors on shared or subscribed calendars

If someone shares a calendar with you through iCloud, you may or may not be able to change its color depending on your permission level. If the owner gave you editing rights, you can change the color. If they only let you view the calendar, the color option will be grayed out or missing.

Holiday calendars and other subscribed calendars from external sources cannot be recolored. These calendars are maintained by their original source, and your iPhone displays them in their default color. If you want a different color for a subscribed calendar, you can create a separate calendar of your own and manually add the events you care about.

Frequently Asked Questions

Will changing a calendar's color affect the events in it?

No. Changing the color only changes how the calendar appears on your screen. All your events, reminders, and details stay exactly the same. The color is just a visual label.

Can I use custom colors instead of the preset ones?

iPhone's Calendar app offers only the preset colors that Apple provides. You cannot create a custom color or upload your own. The available colors are red, orange, yellow, green, blue, purple, and gray.

Why did the color change on my iPhone but not on my Mac?

Color changes usually sync within seconds, but if you see a delay, check that both devices are signed in with the same Apple ID and that both are connected to the internet. If the change still has not appeared after a few minutes, try closing and reopening the Calendar app on your Mac.

Can I change the color of the default calendars like Birthday or Holidays?

The Birthday calendar and system calendars like Holidays cannot be recolored. These are managed by Apple and appear in their default colors. You can only change colors on calendars you created yourself or calendars shared with you that you have editing rights to.

What happens to the color if I delete and recreate a calendar?

When you delete a calendar, all its events are removed. If you create a new calendar with the same name, you will need to assign a color to it again — the old color does not carry over. You can choose the same color or pick a different one.
