Custom Color

we used material angular Library version 0.11.2 to change theme color you can change file /app/app.js

// Use as Primary color
var myPrimary = $mdThemingProvider.extendPalette('green', { 
  '500': '4DB151', 
  'contrastDefaultColor': 'light'
});
 
// Use as Accent color
var myAccent = $mdThemingProvider.extendPalette('yellow', { 
   '500': 'FFDE26'
});
 
// Register the new color palette
$mdThemingProvider.definePalette('myPrimary', myPrimary);
// Register the new color palette
$mdThemingProvider.definePalette('myAccent', myAccent);
$mdThemingProvider.theme('default')
.primaryPalette('myPrimary')
.accentPalette('myAccent');
