Styling ion-label of disabled ion-input

I want to set the opacity of ion-label of disabled ion-input where I have the ion-label in position-floating

  <ion-label position="floating">Submitssion Code</ion-label>
  <ion-input name="{{user.fieldName}}" type="{{user.fieldType}}" [disabled]="true" [value]="user.subCode.value"></ion-input>

I have already set the opacity for ion-input value if the field is disabled using following code in global.scss

.native-input[disabled] {
    opacity: 10 !important;

How can I do the same for ion-label also. I want that label to be visible properly in any color.
