Description

Now with a built-in Focus Timer to boost productivity during calendar events. 🌟✨ KEY FEATURES ✨🌟 🎨 Google Calendar Color Categorization: Assign categories to Google Calendar's existing color palette, making it easier to remember the purpose of each color. For example, red could represent "Critical," blue "Learning," and green "Finances." 🖌️ Custom Color Groups: Add custom color groups that appear in the color picker on calendar events. Each color in the group can be customized with a unique color and label. ⏱️ Focus Timer: Start a productivity timer directly from any calendar event. Track your focus time, get completion sounds, and build better work habits. 🔍 Eyedropper Tool: Pick any color from the screen to use in your custom palette. 🔄 Reset and Disable Options: Clear all custom colors or disable them to use only categorization with Google's default colors. 🧩 Templates for Easy Setup: Pre-made templates including Time Blocking, Priority, Energy Levels, Schedule Type, Projects, Focus Mode, Mood, and Value. ⚠️🚨 IMPORTANT NOTES 🚨⚠️ 🛠️ Dependency on Google Calendar Layout: This extension relies on Google Calendar's current layout. Changes by Google may temporarily break features. If this happens, reach out via email: ali@humanquest.net or visit: https://humanquest.net 💻 Desktop-Only: Chrome extensions don't work on mobile. For mobile, use Google's core colors. 🖌️ Changes Apply to Existing Events Only: New events need to be saved first before colors can be applied. 🙏 Free Extension: This is completely free. Please reach out with issues rather than leaving a negative review. 📋 VERSION UPDATES 📋 🆕 v0.2.4 - Gmail Sidebar Support • Custom colors now appear in Gmail's sidebar calendar — click the Calendar icon in Gmail and your event colors should show up v0.2.3 - Storage & Color Reliability • Fixed custom colors reverting on page refresh — The local storage fallback now correctly reads chunked data, so your colors persist even when sync storage is temporarily unavailable. • Fixed potential infinite loop in storage sync — When Chrome's sync state changes (e.g. signing in/out), the extension no longer risks getting stuck in a recursive loop. • Fixed event viewer dialog coloring — The event detail popup no longer gets incorrectly painted with the event's custom color; only the color dot indicator is updated. v0.2.2 - Storage Health Warnings • Storage Health Warnings - Get notified when storage is running low, blocked, or when using incognito mode.

Everytime I refresh the page, the color assigned is gone - any ideas how to fix this?

Doesn't work. The colors show up on my color options, but when I try to change them, it goes back to the default red. Very frustrating.

I was able to create customized color pallets but I was not able to use them on events. The pallets never showed when I went to change the colors of events.

Would have been a perfect extension...Unfortunately it does not work over multiple weeks in the calendar in "Month" view. If the task spans over multiple weeks, the custom color only applies to the first week in which the task has commenced in "Month" view. The custom colors does show in "Week" view and "Day" view but not in "Month" view. Reallyyyyyyyyyy hoping there could be a fix for this...

I love having the ability to change the colors of the calendar blocks but they change back to grey when my computer goes to sleep for some reason. I use a dual monitor, I'm not sure if that's why or if it is maybe because my account is linked to my iPhone google calendar widget but the response below from the developer to another user who experienced similar and seemingly wrote a general review rubbed me the wrong way. No one is asking for anything to be free and demanding changes, we're letting you know something isn't working. Very rude.

I've been using this extension for months and was working perfectly up until this week - anything new added to my calendar and assigned a colour, will revert back to the original calendar colour when I refresh or close the page. I've checked all the troubleshooting tips in reviews and can't find any issues. Please assist?

Hello Ali, Your extension seems to work well, thank you. But it work only on one calendar and I have 3 of them I access by 3 different Chrome sessions. I have implemented your extension in every chrome session I use. My problem is: when I put one of your color on an appointment,I don't see the same color on my phone nor on another session where I share 2 of my calendars. Is there any way to solve this ? When I change color for appointment using Google standard colors the change is replicated on my phone where I use the app and on the other session where I share my appointment. Thanks for your help.

It works, but I have to change repeating events individually, which is unfortunate. It also tends to revert back to the original color when I refresh my computer.
