How do you change the Stepper color on React Material UI?

Question

In the screenshot above, I am trying to change the step color to either: green for correct, yellow for in-progress and red for incorrect.

How could I do this?

This is a way I used to override it using classes overrides - all other properties remain the same.

const styles = theme => ({
  labelContainer: {
    "& $alternativeLabel": {
      marginTop: 0
    }
  },
  step: {
    "& $completed": {
      color: "lightgreen"
    },
    "& $active": {
      color: "pink"
    },
    "& $disabled": {
      color: "red"
    }
  },
  alternativeLabel: {},
  active: {}, //needed so that the &$active tag works
  completed: {},
  disabled: {},
  labelContainer: {
    "& $alternativeLabel": {
      marginTop: 0
    }
  },
});

class myStepper extends Component {

 render() {
   const { classes } = this.props;
   return(
        
          {this.state.numberTasks.map(label => {
            return (
              
        
          {this.state.labels[label - 1]} //label value here
        
              
            );
          })}
        
);
}

export default withStyles(styles)(myStepper);
