Each user has a color in the Scheduler, so you can tell at a glance whose events are whose. You can change a user's color from the list of users in the Scheduler; their events change color right away.

Change a User's Color
- Open the Scheduler with the calendar icon at the top of the page.
- Under Users, click the colored dot next to the user's name.
- In Choose a color, click a color. It's saved right away.
For a color that isn't in the list, type its code in Custom hex (for example #3b82f6) and press Enter. The events show the color as you type. To close the picker without a change, click the ×.
Event text switches between black and white to stay readable on the color you pick.
Changing colors needs access to edit all calendars. See Can a user edit multiple user calendars?
