将角质材料2更轻/更深的颜色应用于组件

Question

我正在玩物质主题 其中有一个选项可以选择主要，重音和警告，如下所示

$candy-app-primary: mat-palette($mat-indigo, 500, 50, A200);
$candy-app-accent:  mat-palette($mat-pink, A200, A100, A400);
$candy-app-warn:    mat-palette($mat-red);

$candy-app-theme: mat-light-theme($candy-app-primary, $candy-app-accent, 
$candy-app-warn);

 @include angular-material-theme($candy-app-theme);

在我的HTML中

<md-toolbar class="mat-primary">
<!-- above line works perfectly -->
<md-toolbar color="primary">
<!-- above line works perfectly (both are getting 500)-->
<md-toolbar class="mat-primary-lighter">
 <!-- need some kind of implementation to access the weight 50(lighter) or 
A200 (darker)-->
<div class="mat-primary">
 <!-- above is not working on general div bit it should work as it is 
  general class-->

有没有办法在不使用scss之类的东西的情况下生成此功能，如

.someClass { background:mat-color($mat-indigo, 50) }
