我在css组件文件中定义了以下css样式：

::ng-deep .mat-step-header .mat-step-icon-selected,
.mat-step-header .mat-step-icon-state-done,
.mat-step-header .mat-step-icon-state-edit {
  background-color: red !important;
}

::ng-deep .mat-form-field-appearance-outline .mat-form-field-outline {
  color: white !important;
}

::ng-deep .mat-form-field-appearance-outline.mat-focused .mat-form-field-outline-thick {
  color: white !important;
}

::ng-deep
  .mat-form-field-appearance-outline.mat-form-field-invalid.mat-form-field-invalid
  .mat-form-field-outline-thick {
  color: red !important;
  opacity: 0.8 !important;
}

::ng-deep .mat-input-element {
  caret-color: red !important;
}

::ng-deep .mat-form-field-invalid .mat-input-element,
.mat-warn .mat-input-element {
  caret-color: red !important;
}

::ng-deep .mat-form-field-label {
  color: white !important;
}

::ng-deep .mat-form-field.mat-focused .mat-form-field-label {
  color: white !important;
}

::ng-deep .mat-form-field.mat-form-field-invalid .mat-form-field-label {
  color: red !important;
}

::ng-deep .mat-select-value-text {
  color: white !important;
}

::ng-deep .mat-select-arrow {
  color: #fff !important;
}

它运行得很好，但是组件中的所有matinputs（也如matselects）都是有颜色的，我想只对特定的matinputs着色。即使在之后加载的其他组件中，matinputs也会拾取这些颜色变化。
如何控制特定元素的这种情况？
