Angular 2 Material theme refer to color in SCSS

I've created a custom theme with the official guide.

@import '../node_modules/@angular/material/core/theming/_all-theme';
@include mat-core();

$primary: mat-palette($mat-teal);
$accent: mat-palette($mat-deep-orange);
$warn: mat-palette($mat-amber);

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

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


It actually does work. I can set the color of a md-toolbar or md-button with $primary. But I can't access the color variables within a SCSS of a component.

:host {
.mat-grid-tile-header {
background-color: $primary;
}
}


Error in Webstorm:

"Element 'primary' is resolved only by name without using of explicit imports"


Error after build failed: "Undefined variable"

Okey, I somehow have to import it. But I don't get how.

I've tried importing the theme:

@import "../../../theme.scss";
:host {
.mat-grid-tile-header {
background-color: $primary;
}
}


The error in Webstorm has gone away, but a new error after the build appeared:

Module build failed:

Does someone know how to solve this problem? Thanks in advance!
