how to use angular material theme colour variables in other scss files

Question

for a school assignment we need to use angular material. I made a custom theme called: weather-theme.scss

the code in this file is as following:


    @import '~@angular/material/theming';

    @include mat-core();

    // Define the palettes for your theme using the Material Design palettes available in palette.scss
    // (imported above). For each palette, you can optionally specify a default, lighter, and darker
    // hue. Available color palettes: https://material.io/design/color/
    $weather-theme-primary: mat-palette($mat-gray, 800, 700, 600);
    $weather-theme-accent:  mat-palette($mat-amber, 800, 700);

    // The warn palette is optional (defaults to red).
    $weather-theme-warn:    mat-palette($mat-red);

    // Create the theme object (a Sass map containing all of the palettes).
    $weather-theme-theme: mat-light-theme($weather-theme-primary, $weather-theme-accent, $weather-theme-warn);

    // Include theme styles for core and each component used in your app.
    // Alternatively, you can import and @include the theme mixins for each component
    // that you are using.
    @include angular-material-theme($weather-theme-theme);

the theme works.

and i import the theme in styles.scss with the code:


    @import url('https://fonts.googleapis.com/css?family=Nunito&display=swap');

    @import './weather-theme.scss';
    //@import './variables.scss';

    html, body {
        font-family: 'Nunito';
    }

    html, body { height: 100%; }
    body { margin: 0;}

now the problem is, I want to use the Theme variables in other styles like i want to give the body the primary colour from that the code is like this:

    body { 
        margin: 0;
        background-color: $weather-theme-primary;
    }

but when i import the weather-theme.scss the variables are reconized by the scss intellisense it doesn't work, and i get the following error:

Your variable is a map. You have to declare which attribute you want.

background-color: map-get($weather-theme-primary, 100)
