更改 NGX-ADMIN 提供的深色主题的所有（背景、侧边栏、组件等）背景颜色

Question

I have started using the ngx-admin template and it is really great.

However, I want to change one of the templates provided, the dark one. All I want to do is change the main theme colour (which is some shade of blue) to a different dark colour like (black, etc).

Can that be done, if yes, please tell me how?

I have tried reading the docs, but either I am searching it right or it cannot be done.

I am using any kind of template for the first time and any help would be hugely appreciated.

Nebular allows you to create your own custom theme as well has inherit from an already exiting theme. If you're using ngx-admin you can put your own theme in src/app/@theme/styles/themes.scss , inherit from the dark theme and modify just the primary color.

src/app/@theme/styles/themes.scss

$nb-themes: nb-register-theme((

  color-primary-100: #FEEBE0,
  color-primary-200: #FED2C2,
  color-primary-300: #FEB3A3,
  color-primary-400: #FD968C,
  color-primary-500: #FD6767,
  color-primary-600: #D94B57,
  color-primary-700: #B6334A,
  color-primary-800: #92203E,
  color-primary-900: #791336,
  color-primary-transparent-100: rgba(253, 103, 103, 0.08),
  color-primary-transparent-200: rgba(253, 103, 103, 0.16),
  color-primary-transparent-300: rgba(253, 103, 103, 0.24),
  color-primary-transparent-400: rgba(253, 103, 103, 0.32),
  color-primary-transparent-500: rgba(253, 103, 103, 0.4),
  color-primary-transparent-600: rgba(253, 103, 103, 0.48),

), custom-dark, dark); // <- theme name and a parent theme

Then just set your default theme in the theme.module.ts

src/app/@theme/theme.module.ts

NbThemeModule.forRoot({
    name: 'custom-dark',
  }, [ DEFAULT_THEME, COSMIC_THEME, CORPORATE_THEME, DARK_THEME ]
)

Or if you're using the theme drop you can add your custom theme to the header.component.ts file.

src/app/@theme/components/header/header.component.ts

@Component({
  selector: 'ngx-header',
  styleUrls: ['./header.component.scss'],
  templateUrl: './header.component.html',
})
export class HeaderComponent implements OnInit, OnDestroy {

  themes = [
    ...
    {
      value: 'custom-dark',
      name: 'Custom Dark',
    }
    ...
  ];

}
