Exclude Events By Color or Category

Skip events with the selected color or category, or skip all events except those with it.

You find this setting in the Event filters section of the sync configuration. Turn on Exclude events by color/category, then choose what to exclude and a color or category:

• Events with this color/category: Events with the selected color or category are not synchronized. Every other event is.
• All events except this color/category: Only events with the selected color or category are synchronized. Every other event is skipped.

For example, imagine you color your personal appointments blue and your work meetings green. To keep work meetings out of your personal calendar, choose green and Events with this color/category. To sync only your work meetings, choose green and All events except this color/category.

If you choose the calendar's default color, the filter applies to events that have no color of their own.

Exclude by a category

In the Color/Category field, choose Add Custom Category and type the category name, for example "Private". Upper and lower case don't matter.

Outlook, iCloud and CalDAV events can have categories, so the filter checks their categories. Google Calendar has no categories, so Google Calendar events in the same sync are not affected by a category filter.

Colors on Outlook, iCloud and CalDAV calendars

Outlook does not color individual events the way Google Calendar does. Instead, Outlook uses categories, and OneCal maps the default Outlook categories to colors. The color options are labeled with both names, for example "Peacock/Blue category". iCloud and CalDAV calendars have no event colors, so OneCal uses the same category names for them.

When a source of your calendar sync is an Outlook, iCloud or CalDAV calendar, pick one of the colors of the default Outlook categories: Red, Orange, Yellow, Green, Blue, Purple and Gray. Events tagged with that category match the color.
