Feature: Add the option to colour-code individual events.

I think the demand for this feature may be higher than it seems, as votes are fragmented over different feature requests.

This is an attempt to collaboratively compile similar requests. I hope it helps clarify the actual demand for this feature.
Perhaps Proton merges similar feature requests and votes internally, so please let me know if this is not helpful or if there is a better way to clarify the actual demand for features.

• Please provide an option to color code an individual calendar item.
• add color choices for events in the calendar
