I have requirement to take color palette from config file which contains colors based on domain.

Config file is json file placed at root of the project.

In angular material 1 there is a way to generate theme on demand by lazy-generate-theme

Is there any way to do similar in angular material with angular 8?

To use multiple themes check this guide and to generate color palette we often use this Material Design Palette Generator, having those you can configure color theme like this, for example:

...material custom theme implementation from guide...  

...

.red-theme {  
  @include angular-material-theme($red-theme);
  @include custom-components-theme($red-theme);
  ....
}

Now you can use .red-theme class on body to change colors. The best way I found is to prefetch some string like color-palette: "red-theme" from your backend API in APP_INITIALIZER hook (how it works ref) and use it via service:

theme.service.ts   

setColorPalette(colorPalette) {
   const body = document.querySelector('body');
   body.classList.add(colorPalette);
}
