Your Queries, Simplified
Questions? Answers!
Find quick answers to the most common questions about our platform
What is ColorKit ?
ColorKit makes Google Calendar readable at a glance. It adds three things the native UI doesn’t. (1) Day-column colors so each weekday is always the same tint across Day/Week/Month. (2) True any-color task coloring so you’re not stuck with Google’s 1 color for every list. (3) Visual time-blocks (recurring or one-off) that overlay your schedule without creating events. It’s fast, lightweight, and privacy-first (runs entirely in your browser). ColorKit is part of the broader Calendar Extension project at calendarextension.com.
Do you Take or Share any Data ?
No. ColorKit runs 100% client-side. We don’t read, collect, or transmit your calendar contents. Style preferences stay in your browser. Account/billing basics are handled in our portal (payments via Paddle). Only your computer receives any calendar data we receive nothing except to handle payments and subscriptions!
Is There a Free Trial ?
Yes! We have a 7 day free trial and a 7 day money back gurantee so you can test Colorkit before committing
Which browsers and devices are supported?
Google Chrome on desktop only. (No mobile support and no other browsers yet.)
Can I request New Features ?
Absolutely. Use Feedback / Request a Feature from the extension menu or the portal. We prioritize clarity, speed, and zero-clutter improvements.
How Do Day Colors Work
Two ways: 1. You set a color per task list, every task you create instantly changes color You set a color per weekday; the entire column is tinted in Day/Week/Month views. Monday always looks like Monday, Friday like Friday — instant orientation.
Can I Color Google Tasks?
Yes! two ways: 1. You set a color per task list, every task you create instantly changes to that color 2. You want a different color for the task where you can click the task and choose any color for that one.
What are “time-blocks”?
Simple overlays for focus/energy themes — e.g., “Deep Work 9 –1 3” — that can repeat weekly or be unique to a single day. They’re visual only; no calendar events are created.
Is ColorKit affiliated with Google?
No. ColorKit is an independent product, developed under the Calendar Extension brand (calendarextension.com), and is not affiliated with Google LLC.

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.
