Thunderbird colors

Agent virtuel replied
Cris A.

Hey, I'd like to switch from Outlook to Thunderbird. I’ve already tried switching to Thunderbird once when I switched to Linux, but—now to my question: The most important feature for me is being able to use different colors in the calendar to mark appointments. I wasn’t able to get this to work on Linux, even with AI. Isn’t this option available? But if people are switching away from Outlook, surely a small feature like this shouldn’t be a problem?

Can anyone help me with this?

Hi Cris,

In Thunderbird the base color of events is based on the color of the calendar itself, you can't change it per event. As a workaround, you might have separate calendars for different events. If this is not appropriate for you, you can also use categories, these have a separate set of colors, and it's shown on the right side of the event, as a stripe. There are a bunch of built-in categories, but you can modify them and set up your own using the settings.

Hi, and thanks for the reply. As someone switching over—and I think that’s Thunderbird’s goal, too—I still wonder why this isn’t possible. I don’t feel like creating 10 calendars just to have different colors, and besides, syncing with my phone would be a disaster. I noticed the colors on the edges—but they’re so small that they don’t give you an overview. I’d be fine with it if that narrow bar could be expanded to maybe half the width of the field. Is that possible? It’s really a shame, because I actually wanted to switch to Linux, but after 30 years in IT, I’m so used to having that clear overview that it’s essential for me. Thanks
