Steps to reproduce 🕹

Steps:

1. Create a theme
2. Add MuiCheckbox to components
3. Override styles for checked

Current behavior 😯

I want to override the checked and disabled of the CheckBox component as described in the Checkbox API

I have the following code, which is imported in the theme, in the components section. That works fine

import { Components, Theme } from '@mui/material';

export const MuiCheckbox: Components<Theme>['MuiCheckbox'] = {
  defaultProps: {
    disableRipple: true
  },
  styleOverrides: {
    root: ({ theme }) => ({
      borderRadius: 0
      // Here it works but it will override all of the styles which I don't want
      /* '&.Mui-checked': {
        color: '#ff0000'
      }*/
    }),
    checked: ({ theme }) => ({
      // This doesn't work
      color: '#ff0000'
    })
  }
};

The checked does not work in my example. I don't get the desired result, the color should be #ff0000 in this case. But it's still the theme.primary

In the root with &.Mui-checked it works.

Expected behavior 🤔

Selectors for checked should work as well.

The checked should be able to set the style
