You can set different colors for each of your calendars, e.g. blue for your work calendar and green for some personal stuff. This helps you quickly differentiate between different events and add some beauty to your schedule.

How to color-code your calendars:
  1. Tap at the top left to open the sidebar.
  2. Scroll to the bottom and tap Edit Calendars.
  3. Select a calendar and pick the color you like the most.
  4. Tap Save.

You can also pick custom colors for specific events. For example, you may want to set a different color for an especially important meeting or color-code that family dinner you're eagerly awaiting.

Here's how to color-code a specific event:
  1. Tap to create a new event. If you already have an event, tap it and choose Edit.
  2. Under Custom Event Color, pick the desired one.
  3. Tap Save.
