We have system that actually integrates with Google Calendar by creating event there. When create event, we also let user to set the color based on their preference. Technically, we pass colorId when calling Create Event API

However, when we open the created event on Google Calendar GUI (both web and mobile app), it doesn’t use colorId that has been set previously. Looks like their GUI uses color that is set in client

Is there any way to let Google Calendar GUI (both web and mobile app) uses color based on colorId that has been set in the server?

I’ve ensured that colorId has been set correctly in server by calling their Get Event API

Expect: in GUI, use color based on colorId in server
