I Have an event which is three days long. I want to set different background color on each day to the event. It might be event specific and want to assign colors before event creation. Please help. Thanks in Advance.
You can insert custom segments into an event using "active areas":

You can specify the active area position using start/end properties instead of left/right/width and set custom background color and other properties.
