Styling Monthly view

I would like to set a global style for the monthly view where the default text is black and the font size is larger (let’s say 1.5em).

Have tried a few things, none of the below work:

/*h3.tribe-events-month-event-title {
font-size:1.5em !important;
color: black;
}
*/

/*.tribe-events .tribe-events-calendar-month__events {
    font-size: 3em !important;
color: black;
}
*/

/*.h3.tribe-events-calendar-month_calendar-event-title.trive-common-h8.tribe-common-h--alt {
	font-size: 50px;
	color: black;
}
*/

/*.tribe-events-loop .tribe-events-event-meta {
	font-size: 48px;
}
*/
