I am using a custom material-color palette. defined the primary and accent palettes with its default-shade,darker-shade,lighter-shade as below: 

  $my-app-primary: mat-palette($md-lightprimary ,500,900,A700 );
$my-app-accent:  mat-palette($md-lightaccent, 500,900,A100);
$my-app-warn:    mat-palette($md-warn);

/*finalize by creating a $my-app-theme variable that combines our color definitions with the mat-light-theme function,*/
$my-app-theme: mat-light-theme($my-app-primary, $my-app-accent, $my-app-warn);
/* and finally include the result of calling the angular-material-theme function with our $my-app-theme.*/
@include angular-material-theme($my-app-theme);

Questions:

1. If i use in code color="primary" or color="accent" than it sets the default color shade, Question is, how to use the lighter and darker-shades that we have used as part of initial setting of the theme.

2. How to use any other shades from the palette for the primary or accent shades.

Check the code i written below. check the commented lines for usage

Theme.scss 

  $my-app-primary: mat-palette($md-lightprimary ,500,900,A700 );
  $my-app-accent:  mat-palette($md-lightaccent, 500,900,A100);
  $my-app-warn:    mat-palette($md-warn);

  $my-app-theme: mat-light-theme($my-app-primary, $my-app-accent, $my-app-warn); //gives light theme
  $my-app-dark-theme: mat-dark-theme($my-app-primary, $my-app-accent, $my-app-warn); //gives dark version of the above theme

  //apply this class to any element you want to apply dark theme or set class to <body> so apply it to whole site
  .dark-theme { 
      @include angular-material-theme($my-app-dark-theme);
  }
  @include angular-material-theme($my-app-theme); //default theme

As far as I know, there is no easy way to use the non-default shades from your custom palette by simply modifying the HTML (i.e. <button color="primary-lighter"> does not work).

The easiest way I've found is to include custom themes in your Theme.scss file, such as:

$my-accentpalette: ( 50 : #f9f2eb, ... A700 : #ffae71, contrast: ( 50 : #000000, ..., A700 : #000000, ) );

.lighter-style {
        background-color: mat-color($my-accentpalette, 200);
        color: mat-contrast($my-accentpalette, 200);
}

(Note I just picked the '200' entry from the palette, pick whatever you want). Then you can apply the style to any HTML element you want:

<button class="lighter-style">

I also have similar issue with material angular shades. As i cannot find solution (omitting the possibility of using classes that will refer to other theme) in web i used normal scss built-in function such as below: 

@import "./../../my-theme.scss";

a{
 color: darken($accent, 30%);
}
