I'm sharing a google calendar with people who aren't good with computers. Is there an easy way to tell who made what event? I was thinking, is there a way for me to set the default background colour that people make events with? For example can I choose person A to create events with background colour green, person B to create events with back ground colour yellow, person C to create events with back ground colour red etc. If I can't change the default background colour for them is there a way they can do so themselves (all though if it's complicated they may not be able to figure it out)?
