SUMMARY
I've connected some iCloud calendars via CalDAV but enabling the "Calendar Events" plugin in the app settings ends up changing the calendar colors on the server side so all other apps synced to the account end up with Digital Clock's random colors.

STEPS TO REPRODUCE
1. Enable "Calendar Events" plugin on the Digital Clock application.
2. Select check boxes for desired calendars in the "Calendar Event" tab in Digital Clock settings 
3. View calendar events by clicking on Digital Clock widget

OBSERVED RESULT
Synced calendars in other applications adopt calendar color imposed by Digital Clock

EXPECTED RESULT
Digital Clock displays and maintains calendar colors from CalDAV server
