Angular Material comes with pre-built themes to make getting started easy. Once you’ve picked a theme such as indigo-pink, you may want to re-use the base colours in your own components for consistency.

Instead of creating your own scss variables, I would suggest copying base colours from Angular Material.

Let’s copy $primary and $accent colours from Angular Material:

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

// Copy colour palettes individually
$app-primary: mat-palette($mat-indigo);
$app-accent: mat-palette($mat-pink);

// Create variables to use in project
$primary: mat-color($app-primary);
$accent: mat-color($app-accent);Code language: SCSS (scss)

Assuming you’re working on a real project and not a hello-world app, you should consider creating a file to keep these variables.

src/assets/_variables.scssCode language: Bash (bash)

As this is a new file, Angular compiler needs to know about it.

Go ahead and add it to the styles array in your angular.json:

"styles": [ 
    "src/assets/_variables.scss"
]
Code language: JSON / JSON with Comments (json)

Finally, you can import the new variables file in any component and use $primary and $accent:

@import "./../../../assets/_variables";

.entry {
    background-color: $primary;
}Code language: CSS (css)

So there you have it! This is how I re-use colours from Angular Material to keep things consistent.
