You can change the duration bar color using BeforeEventRender:
http://doc.daypilot.org/calendar/event-customization/
This event is called for every event. If you request a calendar refresh after saving the new event it will be fired on the server side as well. You will be able to change the duration bar color using e.DurationBarColor property.
