How to Add More Colors to Apple Calendar

Apple Calendar comes with a limited set of colors, but you can add custom colors on Mac and iPhone

Apple Calendar offers a fixed palette of about a dozen colors on iPhone and iPad, and a slightly larger set on Mac. If you want a color that is not in the standard list — a specific shade of green for work events, a particular purple for personal time, or a custom brand color for a shared calendar — you have options depending on which device you use.

On Mac, you can create truly custom colors by mixing your own RGB values or picking from a color wheel. On iPhone and iPad, you are limited to Apple's preset palette, but you can work around this by using the Notes app or third-party calendar apps that offer more color flexibility. The method you choose depends on whether you need the custom color on one device or across all your devices.

Key Takeaways

Mac Calendar lets you create custom colors by right-clicking a calendar name, choosing "Edit Calendar", and using the color picker to mix RGB values or select from a wheel.
iPhone and iPad Calendar shows only Apple's preset colors, but you can use third-party apps like Fantastical or Google Calendar for more color options.
Custom colors created on Mac will sync to iPhone and iPad through iCloud, so you only need to set them up once on your computer.
If you share a calendar with others, custom colors appear on their devices only if they also use Mac; iPhone users will see the closest preset color instead.

Creating custom colors on Mac Calendar

On Mac, open Calendar and locate the calendar name in the sidebar on the left. Right-click (or Control-click) the calendar name and select "Edit Calendar" from the menu. A window will open showing the calendar details.

Click the colored circle next to the calendar name. A color picker will appear with Apple's standard palette at the top. Below that, you will see a "Color Sliders" option. Click it to reveal RGB sliders, where you can enter exact numbers for red, green, and blue values (each from 0 to 255). You can also click the "Color Wheel" tab to pick a color visually by clicking anywhere on the wheel and adjusting brightness with the slider below it. Once you have the color you want, close the picker and click "Edit" to save.

Syncing custom colors to iPhone and iPad

Custom colors you create on Mac will automatically sync to your iPhone and iPad through iCloud, as long as all devices are signed into the same Apple ID and Calendar sync is turned on. Open Settings on your iPhone or iPad, tap your name at the top, select "iCloud", and make sure "Calendars" is toggled on.

When you open Calendar on your iPhone or iPad after syncing, the custom color will appear in the calendar list, but you cannot edit it from your phone. If you need to adjust the color, you must do so on your Mac and wait for the change to sync back to your mobile devices. The sync usually happens within a few minutes, but can occasionally take longer if your device is offline.

Why iPhone and iPad Calendar does not offer custom colors

Apple Calendar on iPhone and iPad restricts you to a preset palette of about 12 colors. This is a design choice by Apple, likely to keep the mobile interface simple and to ensure colors display consistently across different screen types. Unlike Mac, there is no color picker or RGB input on mobile devices.

If you need more color options on your phone, you have two main alternatives. You can use a third-party calendar app like Fantastical, Google Calendar, or Microsoft Outlook, all of which allow custom colors on iOS. Alternatively, you can create the calendars and colors on your Mac and let them sync to your phone, then use the closest preset color as a workaround when viewing on mobile.

Using third-party apps for more color choices

Fantastical (available on iPhone, iPad, and Mac) lets you set custom colors on any device and syncs them across your Apple devices. Google Calendar also offers a wide color palette and works on both iPhone and web browsers. Microsoft Outlook provides custom colors as well. All three apps sync with your existing Apple Calendar data, so you can view and edit the same calendars in multiple apps.

The trade-off is that you will be using a different app instead of Apple Calendar, which means learning a new interface and potentially paying a subscription fee (Fantastical and some features of Outlook require payment, while Google Calendar is free). If you only need custom colors on your Mac and do not mind the preset colors on your phone, sticking with Apple Calendar and syncing from Mac is simpler and costs nothing.

What happens when you share a calendar with custom colors

If you share a calendar that has a custom color with someone else, the color behavior depends on what device they use. If they view the calendar on Mac, they will see the exact custom color you created. If they view it on iPhone or iPad, the system will show the closest matching preset color from Apple's palette instead.

This can create confusion if the custom color is important for visual organization — for example, if you use a specific shade of teal to distinguish a shared work calendar. Before sharing, consider whether the custom color is essential or if a preset color would work just as well for your collaborators. You can always ask people on your team to use Mac Calendar if color accuracy matters for your workflow.

Editing or removing custom colors

To change a custom color on Mac, right-click the calendar name again, select "Edit Calendar", click the color circle, and adjust the RGB values or wheel position to your new choice. Click "Edit" to save. The updated color will sync to your iPhone and iPad within a few minutes.

To remove a custom color and return to a preset, follow the same steps but click one of the standard colors in the palette at the top of the color picker instead of using the sliders or wheel. This is useful if you want to simplify your setup or ensure the color displays correctly on all devices, including those of people you share the calendar with.

Frequently Asked Questions

Can I create custom colors on iPhone or iPad Calendar?

No, Apple Calendar on iOS and iPadOS only offers preset colors. You must create custom colors on Mac and let them sync to your phone, or use a third-party app like Fantastical or Google Calendar that supports custom colors on mobile devices.

Will custom colors I create on Mac show up on my iPhone?

Yes, if iCloud Calendar sync is enabled on both devices and they are signed into the same Apple ID. The custom color will appear in your calendar list on iPhone, though you cannot edit it from your phone. Sync usually takes a few minutes.

What if someone I share a calendar with uses an iPhone?

They will see the closest preset color instead of your custom color. If the exact color is important for your shared workflow, consider using a preset color instead, or ask them to view the calendar on Mac where custom colors display correctly.

Do I need to pay for an app to get more colors?

No, if you use Mac Calendar and sync to iPhone, custom colors are free. If you want custom colors on iPhone itself, Google Calendar is free, while Fantastical and some Outlook features require a paid subscription.

Can I use a hex color code instead of RGB values?

Mac Calendar does not have a hex input field, but you can convert a hex code to RGB using an online converter and then enter the three RGB numbers into the sliders. For example, hex #FF5733 converts to RGB 255, 87, 51.
