In Google Calendar, you can change the color of any calendar you have access to, whether it is your default calendar, a calendar you created, or a calendar someone shared with you. Changing the color of a calendar will change the color of events on that calendar.
To Change Calendar Color:
- Log in to your Google account and navigate to Google Calendar.
- In the list of calendars on the left side of the screen, hover the cursor over the desired calendar > Click the "Options" icon (3 stacked dots)
- From the resulting menu, choose the desired color from the color palette. The calendar color is changed.
