I have synced up Google Calendar events to my Outlook (Outlook 365 ,16.0.13929.20222).
One feature I extensively use in GCal is to give meetings different color based on topic. Is there a way to sync these colors between Outlook and GCal?
As I know, there seems to be no option in Outlook that could meet it directly. But I found some related articles about third-party tools, please check if it could be helpful to you.

I ended up using Outlook Google Calendar Sync that not only syncs the colors but all kind of calendar events in both ways. I highly recommend using it.
