Color specific date in mat-date-range-input angular 10

I'm currently working on a project that involves using Angular Material's MatDatePicker (range Selection) component to display a calendar with custom styling for specific dates. I've encountered an issue while trying to apply custom CSS classes to certain calendar cells based on specific conditions.

Here's a snippet of my code:

 <mat-form-field appearance="outline" class="col-3 date-picker" (click)="picker2.open()">
          <mat-label>start date</mat-label>
          <mat-date-range-input class="special-element" [rangePicker]="picker2" [dateFilter]="dateFilter">
            <input matEndDate
              [readonly]="true" (dateChange)="changeDate('endDate')">
            <input matStartDate (dateChange)="changeDate('startDate')"[readonly]="true">

          </mat-date-range-input>

          <mat-datepicker-toggle matSuffix [for]="picker2"></mat-datepicker-toggle>
          <mat-date-range-picker #picker2></mat-date-range-picker>
        </mat-form-field>

Any suggestions please ?

You can add .mat-calendar-body-cell-container css declaration in your global
styles.css.

.mat-calendar-body-cell-content {
  color: white;
}


.mat-calendar-body-cell-container {
  background-color: green !important;
}

Edit:

What you can do is the following:

export class YourComponent implements AfterViewInit {
  range =  new FormGroup({
    start: new FormControl(), end: new FormControl()
  });

  @ViewChild('picker2') picker!: MatDatepicker<Date>;

  ngAfterViewInit(): void {
    this.picker.dateClass = (date: Date) => {
      return {
        ['cell-class']: (date.getDate() % 2 === 0)
      }
    }
  }
}

Then on your global styles.css you can define cell-class.

.cell-class {
    background-color: red !important /* you must include important */
}

For this example, it applies color to all even days.
