You can now create your own task & reminder categories, select colors for them and create appointment reminders based on them.
​
Go to Settings> Task & Reminder Categories
​ 
Click Add New Category

Set the details for the category. Determine the name/description, if it's a task or reminder, if it should mark you as busy during that time or not, & if it should display on the calendar. If you want to choose the color for the background and/or text, click on the color box and a color wheel will appear. Click on the color you want, adjust the lightness/darkness and hit Enter/Return. Hit Create when done.
In the 2nd example, you'll see a Reminder creation, which also allows for an Annual Reminder option.
​

Use these custom task categories to create Appointment Reminders.
