How it works
Choose a photo or illustration in the CalHue popup, drop it on the preview, or paste it. Drag to choose which part shows. A veil that follows Calendar’s light or dark theme, and an optional blur, keep events easy to read.
Click Generate palette. CalHue picks colors that belong with your image and keep event titles readable in Google Calendar, in both light and dark themes. Previewing them is free; with Pro, save them as a palette.

The veil follows Calendar’s light or dark theme, and generated colors look the same in both.

Questions
Yes. Your own background image, the veil and blur, grid line colors, six built-in palettes, unlimited palettes of your own, palettes in the calendar color menu and previewing colors made from your image are all free. CalHue Pro is a one-time US$9.99 purchase that saves generated colors, adds palettes to Google Calendar as event labels in one step, and saves themes.
Event labels and calendar colors you set through CalHue are saved by Google in your account, so they show wherever you use Google Calendar, including the phone app. The background image, grid lines and veil show in Chrome on your computer, in the profile where CalHue is installed.
No. The background only shows in your own Chrome. Event labels are visible to you and to people who can make changes to that calendar.
No. CalHue does not read the titles, times or guests of your events. Your image is processed inside the extension and never uploaded. The extension has no account, no ads and no analytics; the only thing it sends is a license check if you use Pro. See the privacy policy.
Never. CalHue only adds labels, when you ask it to, through Google Calendar’s own Labels dialog. It never changes or removes the labels you already have, and never edits your events.
Google Calendar on the web, in Chrome on a computer. The background shows in day, week, month, year, schedule and custom views. Settings, Tasks, Trash and the full event editor keep Google’s own look.
Everything you saved and your current look stay, and labels already in Google Calendar remain yours. Saving generated colors, adding labels to Google and saving or switching themes lock again. Full refunds are available within 14 days of purchase; see the terms.
Earlier versions colored single events inside the extension. Google Calendar now supports custom event colors itself, so CalHue leaves event colors to Google. Your background and palettes carry over, and colors you set on single events are kept as the palette “Legacy event colors”, which you can add to Google in one step. Installations updated from an early version receive Pro at no charge, as thanks for early support.
