How can I add color to events in the .ics Google Calendar files?

As of now, I managed to create an .ics file from a text file that has my work schedule, now the issue is that I would like to distinguish morning and night shifts with colors.

It’s possible in the site itself, but it’s a daunting task to change them all manually, so, if there is a line i can insert programmatically, I would include it to be written in my autoit script.

Is there such a line?
