title: Create Angular Theme without using Material's palette colors
body: <p>Is it possible to create a theme in angular material with your own hex codes? </p>
  
  <p>instead of something like this</p>
  
  <pre><code>$my-theme-primary: mat-palette($mat-blue, 800);
  $my-theme-accent: mat-palette($mat-orange);
  $my-theme-warn: mat-palette($mat-red);
  $my-theme: mat-light-theme($my-theme-primary, $my-theme-accent, $my-theme-warn);
  </code></pre>
  
  <p>do something like this</p>
  
  <pre><code>$my-theme-primary: #1565C0;
  $my-theme-accent: #f4b942;
  $my-theme-warn: mat-palette($mat-red);
  $my-theme: mat-light-theme($my-theme-primary, $my-theme-accent, $my-theme-warn);
  </code></pre>
  
  <p>Basically I have users creating their own themes </p>
