    Theming allows you to change color of complete application from one place. In Angular Material , themes can be configured using $mdThemingProvider in application configuration.

    Configuring theme:

    Theme is configured by using $mdThemingProvider. We can give color palette for each of the configuration method.
    We can set a color for theme.primaryPalette, theme.accentPalette, theme.warnPalette, theme.backgroundPalette
    as given below:

    angular.module('myApp', ['ngMaterial'])
    .config(function($mdThemingProvider) {
      $mdThemingProvider.theme('default')
          .primaryPalette('blue')
           .accentPalette('light-blue')
           .warnPalette('cyan')
           .backgroundPalette('purple');
    	
       $mdThemingProvider.alwaysWatchTheme(true);  
    });
    

     

    Disable theme:

    We can disable theme by calling method disableTheming() as given below:

    angular.module('myApp', ['ngMaterial'])
    .config(function($mdThemingProvider) {
      $mdThemingProvider.disableTheming();
    });

     

    Example of theme:

    
    <link href="~/Content/angular-material.min.css" rel="stylesheet" />
    <body ng-app="myApp">
        <div ng-controller="themeController as crtl" md-theme="{{theme}}" md-theme-watch="true">
            <md-input-container>
                <label>Change theme</label>
                <md-select ng-model="selectedTheme" ng-change="changeTheme()">
                    <md-option ng-value="theme" ng-repeat="theme in themes">{{ theme.name }}</md-option>
                </md-select>
            </md-input-container>
    
            <div>
                <md-button href="#" class="md-raised md-primary">

            .config(function ($mdThemingProvider) {
                $mdThemingProvider.theme('themeRed')
                  .primaryPalette('red')
                  .accentPalette('pink')
                .warnPalette('purple')
                .backgroundPalette('orange');
    
                $mdThemingProvider.theme('themeGreen')
                  .primaryPalette('green')
                  .accentPalette('light-green')
                  .warnPalette('lime')
                .backgroundPalette('teal');
    
                $mdThemingProvider.theme('themeBlue')
                .primaryPalette('blue')
                .accentPalette('light-blue')
                .warnPalette('cyan')
              .backgroundPalette('purple');
    
                //  to cascade down the changes through the DOM.
                $mdThemingProvider.alwaysWatchTheme(true);
    
            })
    
            function themeController($scope) {
                $scope.themes = [
               { name: 'Theme Red', value: 'themeRed' },
               { name: 'Theme Green', value: 'themeGreen' },
                { name: 'Theme Blue', value: 'themeBlue' },
                ];
    
                $scope.selectedTheme = { name: 'Theme Red', value: 'themeRed' };
    
                $scope.changeTheme = function () {
                    $scope.theme = $scope.selectedTheme.value;
                };
