Change colour list

Hello! I have a problem because I can’t change the colour my ion-list.
My .html is like this:


<ion-content class="telefonos" padding>
<ion-list class="MyList" >
    <button ion-item *ngFor="let item of items" (click)="itemTapped($event, item)">
      <ion-icon name="{{item.icon}}" item-left></ion-icon>
        <div align="center">

and my .scss in like this:

    background-color: #58B43F;
    color : #ffffff !important;
    box-shadow : 0px 6px 10px #888888;

box-shadow work fine, but my list is still white and the letters black.

Somebody know what is the problem?
Thanks in advance.

Best regards.

did you know how to change it ?
