Lack of information in docs

For example if I want to change the default colorScheme in: src/admin/app.js

I’ll have to do something like this:

const config = {
  auth: {
    logo: AuthLogo,
  },
  menu: {
    logo: MenuLogo,
  },
  head:{
    favicon: Favicon,
  },
  theme:{
    light: {
      colors: {
        primary100: '#410708',
        primary200: '#830e10',
        primary500: '#CD171A',
        primary600: '#e83a3d',
        primary700: '#f7bdbe'
        buttonPrimary500: '#CD171A',
      },
    },
  },
}

But if I want to do more specific customization, like an specific component of the admin panel, let’s say, this steps backgound color:

I need to know the specific key for that element to be able to change the defaul background color only for it, but the documentation doesn´t have any list of the available keys to customize the admin panel throug this file.
