Can I set different colors for the same category across two Google Accounts?

Yes. Each Google Account lists its own categories separately in the settings menu, so you can pick a different color for a Work category under one account and another color for the same category name under a second account.

Does changing an event color affect other people I share the calendar with?

No. Color choices are stored locally on your device and are not synced to other participants or shared calendar viewers.

My new color does not appear in the day view, only in the month view. Why?

This usually clears up after closing and reopening the Calendar app. If it persists, check that the category still has a checkmark next to it under Open the Settings so it is not hidden from that specific view.

OnePlus: Set Calendar Colors for Appointments and Events

When appointments from different Google Accounts, birthdays, and personal events all appear in the same shade, the Calendar app on your OnePlus gets hard to scan at a glance. Each event category can carry its own color, but the option sits inside the calendar settings and is easy to miss. Without it, a work meeting and a birthday reminder look identical in your day view.

Set Calendar Event Colors by Category auf OnePlus

The stock Calendar app on OnePlus sorts entries by the Google Account and category they belong to, but it applies one default color to everything unless you change it manually. This gets confusing fast once you mix work meetings, personal events, and automatic birthday reminders in the same view.

Custom colors are stored per category and per account, so a color change only affects that specific group of entries. Other events, including ones from a second Google Account, keep their own settings untouched.

p>To assign a color, go to Open the Calendar app ➔ Open the menu ➔ Open the Settings ➔ Choose a category ➔ Tap on Color ➔ Choose a color. Repeat this for every category you want to separate visually, such as birthdays, work, or a shared family calendar.

If entries still show the same color after this change, the sync for that Google Account may not have finished yet, or the category was created after your last sync. A manual sync in the account settings usually resolves that. Color settings are cosmetic only and do not affect reminders, notifications, or event sharing.

Frequently asked questions

Birthday reminders are pulled from your Contacts app through a separate built-in calendar category. Change its color the same way, through Open the Calendar app ➔ Open the menu ➔ Open the Settings, then select the Birthdays category before tapping Color.
