Have not verified this in other configurations, but at least when using the advanced IPersonalizableDayEvent features, when the calendar initially renders for the month, all the event text colors are defaulting to the DeselectedDayTextColor, not the default EventIndicatorTextColor, (nor the overridden property value when using the interface). Selecting a day containing an event and then selecting a different day leaves the correct text color behind. This is reproducible on the sample app -> Advanced Calendar on my Android Emulator for the Pixel 5.
I'd also add that the TodayFillColor behaves similarly. If you remove all the events scheduled for "Today" on the Advanced calendar in the sample app, you'll see the Silver background color only show up after you click on Today and then click away.
