Meet The Team
Hi 👋 I'm Adam Hurley
I built this extension for myself — I’m not a big organization or Google, just a solo-developer trying to make useful apps that help people.
After using it for a year and seeing others on Reddit share the same frustrations, I decided to take a risk and turn it into a real product others can try.
Since this is my first personal project released publicly, I’m invested in feedback and improvements. I welcome any suggestions that help make it better for everyone. Hope it helps you.
Heading
As a long-time Google Calendar user, I wanted to create tools that make it easier to actually work with my calendar — not against it.
While building my main project, Calendar Extension, I found myself using time-blocking more and more. My calendar turned into a mess of fake “placeholder” events just to stay organized. So I built a new tool to fix that — an extension that adds simple, visual blocks instead.
That’s how ColorKit was born — a lighter, more visual toolkit for Google Calendar.
Heading
After releasing the first version, I reached out to early testers and instantly got amazing feedback and feature ideas.
The next big step became clear — tasks. Starting with coloring and day-tinting felt right, but users also wanted smarter ways to plan and label their weeks.
Tasks grew into something bigger: templates, tags, and tools to turn Google Calendar into a real workflow hub.
Heading
With the three main features now live, I’m releasing ColorKit for others to test, explore, and help shape what comes next.
Have ideas to improve Google Calendar? Share them in the feedback board, upvote others, and together we’ll build the ultimate toolkit for Google Calendar.
