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?

Hi Courtney, thank you for the detailed report and for sticking with us! We've just pushed v0.2.3 which specifically addresses this issue, colors should now persist correctly after refresh and page close. The root cause was a storage fallback bug: when Chrome's sync storage was temporarily unavailable, your saved colors were stored in a backup format that the extension couldn't read back on the next page load, so they appeared to "revert." Please update to v0.2.3 (it may take a day or two for the Chrome Web Store to approve) and let us know if the issue persists. If it does, we'd love to help troubleshoot directly, you can reach us at info@humanquest.net and we can walk through a quick diagnostic together. Thanks for your patience!

In Gmail, if you click the Calendar icon it opens up the Google calendar for that day. The Calendar Color extension unfortunately doesn't apply to these events in this view - is it possible for this to be added? Thank you so much!

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

Hi Esha, You are likely experiencing one of the following: - Incognito/Private mode - Storage clears on browser close - Chrome sync disabled - chrome.storage.sync fails, fallback may not work - Storage quota exceeded - Chrome has a 102KB limit for sync storage - Privacy extensions blocking - Some extensions block storage APIs - Browser restrictions - Corporate or enterprise policies Could you double-check whether any of these might apply on your setup? If it’s still happening, feel free to reach out at info@humanquest.net, I’m happy to help troubleshoot or even jump on a quick call to get this sorted.

I love the ability to choose my own color pallete and thanks for creating this! However, it's a little buggy when I try to right-click and select a color, my browser spazzes and I can't click on anything on the page until I do a hard refresh. It kind of gets annoying when I try to do quick changes

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.

Maybe it has already been mentioned, but didn't find it any reviews, when I add a event, the color pallets don't show the new name. But when I edit a meeting, it behaves perfectly. Just getting a handle on it, but so far, I love it.

Thanks for the feedback! This happens because new events don’t technically exist yet until they’re saved, so the extension can’t assign a color at creation time. Once the event is created, it’s detected and colored correctly, which is why editing works as expected. Glad you’re liking it so far 🙂

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 ... Show more

Hi Marc, thanks for taking the time to share detailed feedback. What you’re observing is expected behaviour and is explained in the extension description, but I’ll restate it clearly here for visibility: - Custom colors added by this extension are a desktop-only enhancement. Chrome extensions cannot modify how Google Calendar renders events on mobile devices or in sessions where the extension is not active. - Google’s native colors sync across devices because they are stored by Google. Custom colors added by this extension are an overlay applied in the browser and therefore: -- Do not appear on mobile -- Do not appear in other sessions unless the extension is installed and active there - Cross-device desktop sync is supported via Chrome sync, but it still only applies where the extension is running. If you need colors to appear everywhere (mobile, shared calendars, other devices without extensions), you’ll need to rely on Google’s built-in color palette. The extension is designed to augment, not replace, Google Calendar’s native capabilities. This is a free tool built within the technical constraints imposed by Google and Chrome. I’m always happy to help clarify limitations or improve documentation, and you’re welcome to reach out directly via email instead of assuming this is a bug. Thanks again for trying it. — Ali

This extension is great! My only problem is that it seems I can only create two custom palette groups at a time, and for some reason, I'm unable to name said groups. Even though it gives me the option, it doesn't stay after I click something else. It may just be a user issue on my part, because every other aspect of the extension is awesome.

You just have to scroll down to add a new group.
