Google Calendar lets you color events manually.
Google Calendar lets you choose colors for events and calendars. When the meaning depends on the kind of meeting, the color is usually another choice to make event by event.
Google Calendar event colors
Automatically color Google Calendar events.
Apply colors based on title, description, organizer, attendees, email or domain, calendar, or other matching conditions. Define what a color means once, then let the rule keep running.

Google Calendar doesn't automatically apply colors by meeting type.
Google Calendar gives you colors. Heldrey makes applying them automatic, so the color can follow the kind of meeting instead of another manual choice.
The Heldrey rule
Create automatic color rules for Google Calendar.
Heldrey works on top of Google Calendar. The rule lives in Heldrey; the result happens in the calendar you already use.

Your calendar. Your rules.
Keep event colors consistent as meetings change.
New external meetings become blue automatically. If a meeting changes and no longer matches, Heldrey reevaluates the rule and records what happened.
