为什么我的自定义颜色在我的 Angular 材质主题中不起作用？

Question

我尝试为我的角度材质主题添加更多颜色，我通过 map.deep-merge 函数在 style.scss 中添加了成功颜色

// Custom Theming for Angular Material
// For more information: https://material.angular.io/guide/theming
@use '@angular/material' as material;
@use "sass:map";

@include material.core();

$custom-primary: material.define-palette(material.$light-blue-palette);
$custom-accent: material.define-palette(material.$blue-palette, A200, A100, A400);
$custom-warn: material.define-palette(material.$red-palette);
// extra Colors
$custom-success: material.define-palette(material.$green-palette);
$custom-danger: material.define-palette(material.$orange-palette);



$custom-theme: material.define-light-theme((
  color: (
    primary: $custom-primary,
    accent: $custom-accent,
    warn: $custom-warn,
  )
));


$custom-theme: map.deep-merge(
  $custom-theme,(
    success: $custom-success,
    danger: $custom-danger,
    color:(
      success: $custom-success,
      danger: $custom-danger
    )
  )
    );

@include material.all-component-themes($custom-theme);

一切都正确编译，但是当我尝试将颜色应用于按钮时它看起来像这样

并且不知道为什么。

<button mat-raised-button color="success">Success</button>
<button mat-raised-button color="danger">Danger</button>

目前我正在使用 "@angular/material": "^13.2.4",

我认为只缺少一步：添加.mat-successCSS.mat-danger类：

.mat-success {
  background-color: material.get-color-from-palette($custom-success, 500);
  color: material.get-color-from-palette($custom-success, 500-contrast);
}

.mat-danger {
  background-color: material.get-color-from-palette($custom-danger, 500);
  color: material.get-color-from-palette($custom-danger, 500-contrast);
}

我还删除了map.deep-merge，这在该解决方案中是不必要的。

完整的 theme.scss 文件：

// Custom Theming for Angular Material
// For more information: https://material.angular.io/guide/theming
@use "@angular/material" as material;

@include material.core();

$app-primary: material.define-palette(material.$purple-palette);
$app-accent: material.define-palette(material.$teal-palette, A200);
$app-warn: material.define-palette(material.$red-palette);
// extra Colors
$custom-success: material.define-palette(material.$green-palette);
$custom-danger: material.define-palette(material.$orange-palette);

$custom-theme: material.define-light-theme(
  (
    color: (
      primary: $app-primary,
      accent: $app-accent,
      warn: $app-warn,
    ),
  )
);

@include material.all-component-themes($custom-theme);

.mat-success {
  background-color: material.get-color-from-palette($custom-success, 500);
  color: material.get-color-from-palette($custom-success, 500-contrast);
}

.mat-danger {
  background-color: material.get-color-from-palette($custom-danger, 500);
  color: material.get-color-from-palette($custom-danger, 500-contrast);
}
