Colour Mode decides what the calendar cards read their colour from, and the colour itself is set on each team member or resource.
- Open Appointments and select the view button in the toolbar, which reads Day, Week, Month or Timeline.
- Under Colour Mode, choose Team Member or Resource.
- Open Team Members and select Manage on a person, or Resources and Manage on a resource.
- Beside Calendar colour, select Set, or Change if the person already has one, then pick the colour.
- Select Publish Changes, tick the box in Before You Publish, then select Publish Changes.
Colour Mode only decides where the colour is looked up, so switching it on its own changes nothing until somebody has a colour. Anyone without one keeps the default slate, which is the usual reason half the day goes grey. Remove Colour puts a person back to slate without touching anybody else. View Colour Key, under Colour Mode, lists what every colour on the calendar means, including the red and amber care overrides, which sit above whatever Colour Mode you pick.
