How to change color of chechmark - mdbootstrap checkbox angular 9

This is my part of code:

            <div class="col-sm-12 col-md-3 mt-2 d-flex">
              <div class="box-info">
                <mdb-checkbox [checked]="false" [default]="true">
                </mdb-checkbox>
                <div class="box-body custom-justify-text">
                  <span class="custom-text">
                    test.test
                  </span>
                </div>
              </div>
            </div>
