Apply consistent colour-coding to team calendar events

The problem
Users apply colours inconsistently, making it hard to visually scan for critical events or types across a team. Manual updates are error-prone and don't scale.
How it works
- Define your team's colour mapping for event types or sources.
- Use a delegated service account to list and identify relevant events on each user's calendar.
- Update each event's colourId field via the Calendar API according to your scheme.
- Optionally, trigger updates on a schedule or in response to event creation.
- Communicate the colour legend to all users so the scheme is understood.
What changes
Calendar views are consistent and immediately informative, reducing confusion and misclassification.
Questions people ask
Can I use custom colours?
No, only the predefined set of colour IDs returned by the API are permitted. The UI ignores anything else.
Will users see the colour changes immediately?
Usually yes, but changes may take a few seconds to propagate to all clients, especially mobile apps.
Want this built?
This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
