You can color code events to make it easier to distinguish between teacher's schedules on the calendar. To change the color of an event Employees -> Teachers -> Teacher List -> Click on the row of the teacher whose event color you want to change. Under the "Additional Information" section you will see a field labeled "Calendar Event Color". When you put your cursor in this field a window appears allowing you to select a color for the teacher. After you have selected a new color, click "Save" and the teacher's events will appear in the new color.
