In the past, the clock widget with PIM Events plugin enabled, used to show which calendar an event is from by putting a color strip of the calendar color on the left side of the event. This information is very important and should be visible.
And the color is missing now? Can you share a screenshot of how it looks for you now?
Yes, colors are now missing, but only for some calendars I just noticed. See the attached screenshot.

That's odd. Only for some colors... Feels more like a bug in the models itself than the view.
Not sure. I'm using the default breeze plasma style, by the way. I tried disabling and renabling the visible calendar events as well as reenabling the PIM Events plugin but neither did anything.
I finally found a workaround which was to change the calendar's color ("set folder color"). After restarting plasma the calendar colors now appear in the digital clock events section.
Moving to KDEPIM as it seems like the data model is at fault here.
