CSS style for QEdit calendarPopup

Is there a way to style the text (month and year text color at the top specifically).

As far as I understand the popup is created dynamically when you click the dropdown button

I tried using the following code:

QDateEdit::down-down {
    color: black;
}

and

QCalendarWidget {
    color: black;
}

This doesn't work. Is there even a way to style this popup with stylesheet?
