Answer 1

1.) First go through theme documentation here

2.) Pick colors from palette (link)

3.) Create yr own custom theme with colors you want and define it inside app.config.

app.config(function($mdThemingProvider) {

    $mdThemingProvider.theme('default')
          .primaryPalette('blue')
          .accentPalette('indigo')
          .warnPalette('red')
          .backgroundPalette('grey');

    $mdThemingProvider.theme('custom')
          .primaryPalette('grey')
          .accentPalette('deep-purple')
          .warnPalette('green')

    //create yr own palette 
    $mdThemingProvider.definePalette('amazingPaletteName', {
        '50': 'ffebee',
        '100': 'ffcdd2',
        '200': 'ef9a9a',
        '300': 'e57373',
        '400': 'ef5350',
        '500': 'f44336',
        '600': 'e53935',
        '700': 'd32f2f',
        '800': 'c62828',
        '900': 'b71c1c',
        'A100': 'ff8a80',
        'A200': 'ff5252',
        'A400': 'ff1744',
        'A700': 'd50000',
        'contrastDefaultColor': 'light',    // whether, by default, text         (contrast)
                                    // on this palette should be dark or light
        'contrastDarkColors': ['50', '100', //hues which contrast should be 'dark' by default
         '200', '300', '400', 'A100'],
        'contrastLightColors': undefined    // could also specify this if default was 'dark'
    });

   $mdThemingProvider.theme('custom2')
        .primaryPalette('amazingPaletteName')

}

4.) Then on yr html u can just use these theme

<div>
   <md-button class="md-primary">I will be blue (by default)</md-button>
   <div md-theme="custom">
      <md-button class="md-primary">I will be grey(custom)</md-button>
   </div>
   <div md-theme="custom2">
      <md-button class="md-primary">I will be red(custom2)</md-button>
   </div>
</div>
