I would like to color the tasks shown on the calendar view by the task date that is being represented. We have multiple dates fields associated with each task. We can see them all in one view, but we would like to be able to see what type of date field is being represented by the color. For example, we have two custom date fields called, "Event Begins" and "Promo Begins". I would like all of the "Event Begins" items to be green and all the "Promo Begins" dates to be orange.
