Event on the calendar by colour

I wish to mark some events by colour on my calendar.

In the same way that I can change the colour of event on Google calendar.

Can I do it in glide?

I think the easiest would be to use emoji. An IF column can look at a specific column value and return a specific emoji, such as :red_circle::green_circle::large_blue_circle::red_square::green_square::blue_square:. Then you can append that to the beginning of the event title using a template column. Then display that template in your calendar.
