Angular - Material: Progressbar custom color?

I am now trying for hours. I use Material2 and simply want to change the color of the progress-bar. I know there are those themes (primary/accent/warn) but I want to have a cutom color (green) for my progressbar.

I already tried the wierdest css-combinations.. but with no effort. Maybe someone had the same problem?

I can suggest to change one of the premade primary/warn/accent colors to your custom color.

In your styles.scss (if your style file is css you will have to change it to support scss):

  @import '~@angular/material/theming';
  // Plus imports for other components in your app.

  // Include the common styles for Angular Material. We include this here so that you only
  // have to load a single css file for Angular Material in your app.
  // Be sure that you only ever include this mixin once!
  @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.

  $mat-blue: (
    50: #e3f2fd,
    100: #bbdefb,
    200: #90caf9,
    300: #64b5f6,
    400: #42a5f5,
    500: #2196f3,
    600: #1e88e5,
    700: #1976d2,
    800: #1565c0,
    900: #0d47a1,
    A100: #82b1ff,
    A200: #448aff,
    A400: #2979ff,
    A700: #2B66C3,
    contrast: (
      50: $black-87-opacity,
      100: $black-87-opacity,
      200: $black-87-opacity,
      300: $black-87-opacity,
      400: $black-87-opacity,
      500: white,
      600: white,
      700: white,
      800: $white-87-opacity,
      900: $white-87-opacity,
      A100: $black-87-opacity,
      A200: white,
      A400: white,
      A700: white,
    )
  );

  $candy-app-primary: mat-palette($mat-blue, A700);
  $candy-app-accent:  mat-palette($mat-orange, A200, A100, A400);

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

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

You can use ::ng-deep selector to achieve what you want, this answer has some info on it.

How I did it:

CSS

::ng-deep .mat-progress-bar-fill::after {
    background-color: #1E457C;
}

::ng-deep .mat-progress-bar-buffer {
    background: #E4E8EB;
}

::ng-deep .mat-progress-bar {
    border-radius: 2px;
}

HTML

<mat-progress-bar  mode="determinate" value="{{progress}}"></mat-progress-bar>

And the result is this:

EDIT:

I found a way to avoid using ::ng-deep as it will be removed from angular soon. It seems that if you move your style from your component.css file to the global styles.css file it will work without ::ng-deep.

So, a style defined above can change in

mat-progress-bar .mat-progress-bar-buffer {
  background: #E4E8EB;
}

Move it to styles.css and it will be applied like this:

This worked for me on a new project. I did not checked specifically with the old code but the conditions are the same and there is no reason for it not to work.

Since nobody mentioned so far...

He's how I solved it.

@Meet Dave is right about his approach. But you should use encapsulation: ViewEncapsulation.None (disables css modules)

Something like this:

Component

@Component({
  selector: '...',
  templateUrl: '...',
  styleUrls: ['...'],
  encapsulation: ViewEncapsulation.None,
})

Sass (in my case)

.audio-progress-bar {
  &.mat-progress-bar {
    height: 10px;
  }

  .mat-progress-bar-fill::after {
    background-color: #37474f;
  }

  .mat-progress-bar-buffer {
    background-color: #90a4ae;
  }

  /* remove animation and the dots*/ 
  .mat-progress-bar-background {
    animation: none;
    background-color: #eceff1;
    fill: #eceff1;
  }
}

View

<mat-progress-bar
  class="audio-progress-bar"
  mode="buffer"
></mat-progress-bar>

Update:

Avoid using deep, TL;DR: Deep is technically invalid (like, deeprecated :p)

For more info refer: The use of /deep/ and >>> in Angular 2

Now, to change the color of mat-progress bar, Here is how I got it working,

Head over to your styles.scss file (or the main css/scss file in your project)

Add this class -->

.green-progress .mat-progress-bar-fill::after {
    background-color: green !important;
}

Your mat-progress should use the above class, like -->

<mat-progress-bar class="green-progress" mode="indeterminate"></mat-progress-bar>

For me I just need to put in CSS this rule:

div.mat-progress-bar-primary.mat-progress-bar-fill.mat-progress-bar-element::after{ background-color: green; }

But clearly is easier if you use a theme.

Angular 7 and Material 7.1.1

 ::ng-deep .mat-progress-spinner circle, .mat-spinner circle{
        stroke: green !important; 
}

Angular 8 solution:

for me it was putting my styling in a top level .scss file. Also had to select in .scss as follows:

html:


<mat-progress-bar [ngClass]="passwordStatusBarColor" 
                  aria-label="Password strength meter"
                  mode="determinate"
                  [value]="progress">
</mat-progress-bar>

<!--passwordStatusBarColor could be 'weak', 'weakest', etc. with a corresponding rule-->

styles.scss:

.weakest {
  .mat-progress-bar-fill::after {
    background-color: yellow;
  }
}

You can override only progress bar backgroud-color through this method added custom class then apply css by combination of tag and class like-

<mat-progress-bar class="my-color" mode="determinate" value="40"></mat-progress-bar>

Change into style.css

mat-progress-bar.my-color .mat-progress-bar-fill::after { background-color: green; }
