Change ion-view header color in ionic

Some ways to do this:

1. You could add the ion-nav-bar to each view.

   <ion-view view-title="Page 1">
     <ion-nav-bar class="bar-balanced">
       <ion-nav-back-button></ion-nav-back-button>
     </ion-nav-bar>
     <ion-content>
       ...
     </ion-content>
   </ion-view>
   

   Codepen example

2. You could also update the background-color (and any other properties) by using ng-style

   Main navbar:

    <ion-nav-bar class="bar-positive" ng-style="{'background-color': viewColor}">
       <ion-nav-back-button></ion-nav-back-button>
     </ion-nav-bar>
   

   CSS:

   .nav-bar-block, .bar {
     background-color: inherit !important;
   }
   

   Controller:

   $scope.$on('$ionicView.beforeEnter', function() {
       $rootScope.viewColor = 'green';
   }); 
   

   Codepen example

Could not find a clean solution for this, but one hack might be to use the $stateChangeStart event and set the class name manually.

angular.module('starter')
.run(function ($rootScope) {
    var element;
    $rootScope.$on('$stateChangeStart', function (event, next) {
        if (next.name) {
            element = angular.element(document.querySelectorAll('ion-header-bar'));
            switch(next.name) {
                case 'tab.chats':
                    element.removeClass('bar-positive');
                    element.removeClass('bar-balanced');
                    element.addClass('bar-calm');
                    break;
                case 'tab.dash':
                    element.removeClass('bar-calm');
                    element.removeClass('bar-balanced');
                    element.addClass('bar-positive');
                    break;
                default :
                    element.removeClass('bar-calm');
                    element.removeClass('bar-positive');
                    element.addClass('bar-balanced');
            }
        }
    });
});

EDIT The idea is same for sidebar template,

Updated fiddle

Notice the line

<ion-nav-bar class="bar-positive">

in menu.html template, it denotes the base header color class. but subsequent changes to pages i.e states header color needs to be changed manually in $stateChangeStart event,

code:

.run(function ($rootScope) {
    var element;
    $rootScope.$on('$stateChangeStart', function (event, next) {
        if (next.name) {
            element = angular.element(document.querySelectorAll('ion-side-menu-content ion-header-bar'));
            console.log(element);
            switch(next.name) {
                case 'app.search':
                    element.removeClass('bar-positive');
                    element.removeClass('bar-energized');
                    element.removeClass('bar-dark');
                    element.addClass('bar-assertive');
                    break;
                case 'app.browse':
                    element.removeClass('bar-calm');
                    element.removeClass('bar-assertive');
                    element.removeClass('bar-dark');
                    element.addClass('bar-energized');
                    break;
                default :
                    element.removeClass('bar-positive');
                    element.removeClass('bar-energized');
                    element.removeClass('bar-assertive');
                    element.addClass('bar-dark');
            }
        }
    });
});

1. here the state name is checked to see which page is activating ex. app.search
2. then according to requirement specific color class is assigned removing other color classes.

ionic color options

hope this helps.

I modified the solution of @shakib to fit my needs, in my case the user sets the theme by clicking the app logo and thus the bar color should change. If this is your case you don't need to do the switch case because you want to change all views

$rootScope.$on("$stateChangeStart", function (event, toState) {
          var element;
          if (toState.name){
              element = angular.element(document.querySelectorAll('ion-side-menu-content ion-header-bar'));
              if (debugMode) console.log(element);
              // I get the bar-class from my localStorage where I keep the user settings
              var saved_bar_class = $localStorage.get('bar-class','bar-calm');

              element.removeClass('bar-pink');
              element.removeClass('bar-calm');
              element.addClass(saved_bar_class);
          //    Here We could use a Switch Case on toState.name to put a different color to each state

          }
      });

Also when the user clicks the app logo I want to immediately change the bar color in order to give feedback to the user of what that button do. The above code won't do that because we haven't changed state yet, to fix this just add this code to your 'change theme' function

$scope.changeAppTheme = function () {
        var element;
        element = angular.element(document.querySelectorAll('ion-side-menu-content ion-header-bar'));
            // some code to select the theme
            element.removeClass('bar-pink');
            element.removeClass('bar-calm');
            element.addClass('bar-pink');
            // some other code
    };

In this case I just have two colors, the ionic calm and a pink one that I defined Hope this helps someone

Try using the following code:

<ion-view>
  <ion-header-bar class="bar-assertive">
    <h1 class="title">Search</h1>
  </ion-header-bar>
  <ion-content>
    <h1>Search</h1>
  </ion-content>
</ion-view>

if you are using different states and each state has a different controller than just have a $scope variable like $scope.stateone = "true" etc. Then on your ion-nav-bar use ng-class="{'bar-positive': stateone, 'bar-stable': statetwo, 'bar-assertive': statethree}". ng-class takes classes and an expression, whichever expression is true that is the class that is assigned. you can use ng-class with any boolean expression. this is how you can have a different color on each page.

You can override $bar-stable-text color (taken from _variables.scss from ionic lib)

For example, in your scss change

$bar-stable-text: green !default;
