How do I use a material theme colors in my css in Angular2?

Question

Let's say I need to use the mat-primary color as a background of a div using a css/sass class, how do i reference it? I thought something like:

@import '~@angular/material/prebuilt-themes/deeppurple-amber.css';

.a-class{
  background-color: $mat-primary;
}

but miserably fails.

Answer 1

You have to first import the theme with

@import '~@angular/material/prebuilt-themes/deeppurple-amber.css';

Then you have to define a mixin like

@mixin primary-color($theme) {

  $primary: map-get($theme, primary);

  //Then you can use `mat-color` to get the `primary` color
  .a-class {
    background-color: mat-color($primary);
  }
}
