How to create a custom color theme with angular5 and angular materials

In order to use a custom hex palette for an Angular – Material you will need to define the different shades as well as contrast colors for the palette, even if you only want one color. I’d suggest using at least 3 colors (light, normal, dark) so that it works flawless with Material’s built in animations:

// below defines your custom color to build a theme palette from
$my-blue: (
  50: #7fdddd,
  100: #7faedd,
  200: #7f7fdd,
  300: #7faedd,
  400: #7faedd,
  500: #7faedd,
  600: #7faedd,
  700: #7faedd,
  800: #7faedd,
  900: #7faedd,
  A100: #7faedd,
  A200: #7faedd,
  A400: #7faedd,
  A700: #7faedd,
  contrast: (
    50: white,
    100: white,
    200: white,
    300: white,
    400: white,
    500: white,
    600: white,
    700: white,
    800: white,
    900: white,
    A100: white,
    A200: white,
    A400: white,
    A700: white,
  )
);
// below creates a primary palette with three shades of blue
$my-primary: mat-palette($my-blue, 100, 50, 200);
