[O] Color agenda items

[Maximilian Matthe]

Hi all,

I've imported school holidays from .ics into my org-mode setup. They do
show up in the agenda. I would like to have a special color for all
holiday entries in the agenda. Maybe I can add this in the
PROPERTIES-Drawer? 

And another related question: Is it possible to give the start and end
of a date (e.g. holidays) a different color than the intermediate days?

Regards, Max
