Choosing the right colors in Google Calendar helps you spot meetings at a glance and keep work, personal, and shared events apart. In this guide, you’ll learn how to add, change, and organize Google Calendar colors so your schedule is clear and quick to read.

Why are Google Calendar colors important?

Google Calendar colors are important because:

  • They help us see what kind of event it is (work, personal, shared).

    Using different colors for each type of event lets you tell them apart in seconds. When you open the calendar, your brain links the color to the category without reading the text, so you can stay focused on more important details.

  • Spot free time and busy blocks faster
    Using a long block of the same color to show where you are booked, while empty gaps or lighter shades reveal free slots, makes planning a new meeting or personal task quicker.

  • Reduce mix-ups by giving each calendar its own color

    If you assign one color to each calendar (for example, blue for work and green for family), so meetings never overlap unnoticed. If an invite appears in the wrong color, you know right away that it landed on the wrong calendar and can move or delete it before conflicts happen.

  1. Open Google Calendar on the web by visiting this URL: https://calendar.google.com/calendar
    Google Calendar Home

If you’re looking for unique colors, you can visit the Tailwind CSS colors page and choose one of the colors available. You can also use tools like Color Hunt to explore unique color palettes.

Regardless of the page you use to find unique colors, you can directly add them to Google Calendar via the method above.

Note: By using the “Add custom color”, you can only add one custom color to your Google Calendar.

Can I use the custom color on new/existing events?

Absolutely! Right after you add the custom color following the steps above, you can use that color on new or existing events.

For example, I just added a custom color of #6366f1 to my Google Calendar. If I create or edit an event (as shown below), I can select the new color for my events.

Google Calendar - Custom color

How to sync colors between calendars?

You can use a calendar sync tool like OneCal to synchronize events between calendars. OneCal can synchronize events between calendars and carry the colors as well.

You can also change the color of the synced events, in case you want to distinguish them from the original events.
