How can I change the default placeholder color in md-input-container from grey to Material Blue? I have followed the instructions in the documentation and created my own theme, but none of the code snippets seems to work. What am I doing wrong?
mainApp.config(function($mdThemingProvider) {
$mdThemingProvider.theme('alt')
.backgroundPalette('blue-grey')
.primaryPalette('orange')
.accentPalette('green');
});
<md-input-container class="md-block" flex="30" md-theme="alt">
<input required type="text" placeholder="Week"
/>
<div ng-messages="$error">
<div ng-message="required">This is required.</div>
</div>
</md-input-container>
