How to color-code events in Apple Calendar

When creating entries in a digital calendar for the first time an obvious action would be to color-code different kinds of events, perhaps by using a popup menu that has categories names and associated colors. This would provide at-a-glance access to the activities you have slated across a day, week, or month, and you can also get that same insight from other people’s shared calendars. Apple offers color-coding in the Finder with Tags, and similar color-coding appears in most software that lets you create entries that work well with category divisions.

Well, you can’t with Apple’s ecosystem of Calendar apps. The DNA of internet-based calendars, CalDAV, doesn’t include a generic capacity to mark events with colors or categories. Apple opted not to extend its version to include them. Google made a different choice, letting you mark colors event by event. You won’t see these colors in Apple’s Calendar apps, but if you use the Google Calendar web app or Fantastical in iOS, iPadOS, or macOS, you can see Google Calendar entries’ colors.

There’s a way around this, though it’s tedious: create a separate calendar for each kind of task you want to color code. When creating new events, make sure to select the calendar associated with that kind of activity. You can set a custom color for each calendar:

• In macOS, Control/right-click the calendar entry in the left-hand sidebar and choose an existing color or choose Custom Color.
• In iOS/iPadOS, tap the Calendar button at the bottom of the Calendar app, tap the i info icon to the right of a calendar entry, and tap the name under Color. You can choose a color from the list or tap Custom.

If you’re sharing calendars with other people, you just have to issue a bunch of calendar invites. Each person can set unique colors for the shared calendars they view–they’re not required to honor the choices you make.
