title: Ionic 4 ion-DatePicker customize color
body: <p>I'm looking to see if I can change the datepicker colors in ionic 4 to another color with css.</p>
  
  <p>Here is my code;</p>
  
  <pre><code>&lt;ion-item&gt;
      &lt;ion-icon name="time"&gt;&lt;/ion-icon&gt;
      &lt;ion-label style="padding-left: 10px;"&gt;Pickup Time&lt;/ion-label&gt;
      &lt;ion-datetime class="picker-color" [value]="today" minuteValues="0,15,30,45" displayFormat="h:mm:a"&gt;&lt;/ion-datetime&gt;
  &lt;/ion-item&gt;
  </code></pre>
  
  <p>Please see photo; I want to be able to change the color of the selection from Yellow to Red.</p>
