I’m using Calendar 2.1.3 under NC 20.0.7. If I change the color for a calendar item, it appears as the background color for the item title in the day and week view, but not the month view. In the month view the color appears only as a small colored dot or bullet beside the title. I’m a little color-blind, and the small dots don’t stand out very well for me. I would like to suggest that the month-view presentation should use the same color highlighting scheme as the day and week view, for better visibility and for consistency with the other views.
