Calendar colour rules

Colour rules make Google Calendar easier to read.

A useful calendar colour system should answer one question quickly: what kind of time is this? ClearCal applies colour rules to Google Calendar events so your week has visible structure before you inspect each event.

The five ClearCal rules

1. External meetings: calls with people outside your organisation, such as customers, partners, and sales conversations.
2. 1:1 meetings: smaller check-ins that usually need a different kind of preparation than group meetings.
3. Internal group calls: team meetings, planning sessions, standups, and recurring company conversations.
4. Calendar blocks: solo time such as focus work, travel, admin, reminders, or protected project time.
5. Weekend meetings: events that may need extra attention because they sit outside a normal working week.

Why rules beat manual event colours

Manual colour-coding works until the calendar changes. Then new events, rescheduled meetings, and recurring calls drift out of sync. ClearCal refreshes the upcoming window automatically, so the colour system stays current with less maintenance.

Free and Pro rule coverage

The Free plan keeps the basics available with two colour rules and a 7-day lookahead. Pro unlocks all five rules, a 28-day lookahead, and a colour picker for choosing the Google Calendar colours that match how you scan your week.
