GCal Pro: Custom Colors for Google Calendar

GCal Pro helps you customize Google Calendar event colors beyond the default palette, making your schedule easier to scan, organize, and understand at a glance.

If you rely on Google Calendar every day, limited color options can make everything blend together. GCal Pro gives you more control over event colors, so your calendar works the way you think.

✨ What you can do with GCal Pro • Add unlimited custom colors to Google Calendar events • Go beyond Google’s default color palette • Use HEX and RGB color values for precise color control • Save custom colors to your Chrome profile, so they sync automatically across your signed-in Chrome browsers • Reuse saved colors anytime without re-creating them • Edit a saved color once and automatically update all events with the same title • Improve visual clarity for work, personal time, or multiple calendars

All color changes are applied directly inside Google Calendar and update instantly.

⚡ Designed to feel native

GCal Pro integrates seamlessly into the Google Calendar interface. There’s no setup, no separate dashboard, and no learning curve — it simply adds more flexibility to the calendar you already use.

🔒 Privacy-first • No accounts required • No tracking or analytics • No external servers • All customization happens locally in your browser

Your calendar data stays private.

📝 Important notes • This extension works only on the desktop web version of Google Calendar (calendar.google.com). • It does not work on the mobile version or the Google Calendar mobile apps (Android or iOS).

Enhance your schedule with more custom colors, better visual organization, and full control over how your Google Calendar looks.
