@DarkHelmet1 Gold is dedicated for today or current moment. Blue(dodgerblue) is for weekend_1 Red(crimson) is for weekend_2 You can find those colors in module’s css. So; you can override like this; .CX3A .cell.today .cellDay { color: white; /* It was var(--todayColor) */ } .CX3A .cell.weekend_1 .cellDay { color: white; /* It was dodgerblue */ } .CX3A .cell.weekend_2 .cellDay color: white; /* It was crimson */ } The reason why your selector .CX3A .cellheader .cellHeaderMain .cellDate didn’t work, is this; .cellHeader is right, not .cellheader.
