Clone Events Colors
Choose to give cloned events a custom color so you can easily distinguish them from real events in your calendar.


With OneCal's Calendar Sync feature, you can make your synced events stand out by giving them a custom color. This means you can choose a special color for the events that are copied from one calendar to another.
Let's say your real events in your calendar are in blue, but you want your cloned events to be in green. By selecting this custom color option, all the events that get duplicated from one calendar to another will be shown in the color you've chosen, like green. This makes it super easy to tell which events are the originals and which ones are the duplicates, helping you stay organized and on top of your schedule
Event colors on Outlook calendars
Outlook displays event colors through categories. For Outlook to display the OneCal event colors correctly, the following categories must exist in your Outlook account, with these exact names:
- Blue category
- Gray category
- Green category
- Orange category
- Purple category
- Red category
- Yellow category
The names are case-sensitive and must match exactly. Other categories are not supported.
To find your Outlook categories, log in on Outlook web, click the cog icon next to your profile picture, then open Categories. Depending on your Outlook version, it appears under Account or General.
