This is my code to auto color code my Google Calendar events after creating one on my phone/computer. One less step needed when creating future calendar events

Steps to implement code:

1. Go to script.google.com and make a new script. I titled mine "Google Calendar Personal Color Coding"
2. Copy and paste the code above
3. Within the code, adjust the:

• "keyword" (aka keywords you want to adjust color based off of for the calendar event title)
• "CalendarApp.EventColor.COLOR" to your preferences

4. Save
5. Set a "Trigger" to have this run on every new calendar update, to run in real time:

• Function: ColorEvents
• Select event source: From calendar
• Event calendar details: Calendar updated
• Failure notifications: Notify my daily
• Save

And done! Have fun organizing your life :)
