Colors to differentiate Premiers and Finales in Calendar

Would be great if the colors were user selectable, but I would be more than happy with some sane defaults to be able to see at a glance if it’s a new series, season, or episode, or if something is ending. Finale, Mid-Season finale, Series Finale.

Even something like green for something starting, and red for something ending would be a huge help. We can’t filter for these options (other than premiers), so colors seems to be the easiest fix.
